+
+## 0.5.0
+
+[Commits](https://github.com/xmldom/xmldom/compare/0.4.0...0.5.0)
+
+### Fixes
+- Avoid misinterpretation of malicious XML input - [`GHSA-h6q6-9hqw-rwfv`](https://github.com/xmldom/xmldom/security/advisories/GHSA-h6q6-9hqw-rwfv) (CVE-2021-21366)
+ - Improve error reporting; throw on duplicate attribute\
+ BREAKING CHANGE: It is currently not clear how to consistently deal with duplicate attributes, so it's also safer for our users to fail when detecting them.
+ It's possible to configure the `DOMParser.errorHandler` before parsing, to handle those errors differently.
+
+ To accomplish this and also be able to verify it in tests I needed to
+ - create a new `Error` type `ParseError` and export it
+ - Throw `ParseError` from `errorHandler.fatalError` and prevent those from being caught in `XMLReader`.
+ - export `DOMHandler` constructor as `__DOMHandler`
+ - Preserve quotes in DOCTYPE declaration
+ Since the only purpose of parsing the DOCTYPE is to be able to restore it when serializing, we decided that it would be best to leave the parsed `publicId` and `systemId` as is, including any quotes.
+ BREAKING CHANGE: If somebody relies on the actual unquoted values of those ids, they will need to take care of either single or double quotes and the right escaping.
+ (Without this change this would not have been possible because the SAX parser already dropped the information about the quotes that have been used in the source.)

+
+[Commits](https://github.com/xmldom/xmldom/compare/v0.1.27...v0.1.31)
+
+The patch versions (`v0.1.29` - `v0.1.31`) that have been released on the [v0.1.x branch](https://github.com/xmldom/xmldom/tree/0.1.x), to reflect the changed maintainers, **are branched off from [`v0.1.27`](#0127) so they don't include the breaking changes introduced in [`xmldom-alpha@v0.1.28`](#0128)**:
+
+## Maintainer changes
+
+After the last commit to the original repository on the 9th of May 2017, the first commit to is from the 19th of December 2019. [The fork has been announced in the original repository on the 2nd of March 2020.](https://github.com/jindw/xmldom/issues/259)
+
+The versions listed below have been published to one or both of the following packages:
+-
+-
+
+It is currently not planned to continue publishing the `xmldom-alpha` package.
+
+The new maintainers did not invest time to understand changes that led to the last `xmldom` version [`0.1.27`](#0127) published by the original maintainer, but consider it the basis for their work.
+A timeline of all the changes that happened from that version until `0.3.0` is available in . Any related questions should be asked there.

+### DOM Parsing and Serialization
+
+From the [W3C DOM Parsing and Serialization (WD 2016)](https://www.w3.org/TR/2016/WD-DOM-Parsing-20160517/) `xmldom` provides an implementation for the interfaces:
+- `DOMParser`
+- `XMLSerializer`
+
+Note that there are some known deviations between this implementation and the W3 specifications.
+
+Note: [The latest version of this spec](https://w3c.github.io/DOM-Parsing/) has the status "Editors Draft", since it is under active development. One major change is that [the definition of the `DOMParser` interface has been moved to the HTML spec](https://w3c.github.io/DOM-Parsing/#the-domparser-interface)
+
+
+### DOM
+
+The original author claims that xmldom implements [DOM Level 2] in a "fully compatible" way and some parts of [DOM Level 3], but there are not enough tests to prove this. Both Specifications are now superseded by the [DOM Level 4 aka Living standard] wich has a much broader scope than xmldom.
+
+xmldom implements the following interfaces (most constructors are currently not exposed):
+- `Attr`
+- `CDATASection`
+- `CharacterData`
+- `Comment`
+- `Document`
+- `DocumentFragment`
+- `DocumentType`
+- `DOMException` (constructor exposed)
+- `DOMImplementation` (constructor exposed)
+- `Element`
+- `Entity`
+- `EntityReference`
+- `LiveNodeList`
+- `NamedNodeMap`
+- `Node` (constructor exposed)
+- `NodeList`
+- `Notation`
+- `ProcessingInstruction`
+- `Text`
+
+more details are available in the (incomplete) [API Reference](#api-reference) section.
+
+### HTML
+
+xmldom does not have any goal of supporting the full spec, but it has some capability to parse, report and serialize things differently when "detecting HTML" (by checking the default namespace).
+There is an upcoming change to better align the implementation with the latest specs, related to .
+
+### SAX, XML, XMLNS
+
+xmldom has an own SAX parser implementation to do the actual parsing, which implements some interfaces in alignment with the Java interfaces SAX defines:
+- `XMLReader`
+- `DOMHandler`
+
+There is an idea/proposal to make ti possible to replace it with something else in

+
+Higher level content negotiation based on [negotiator](https://www.npmjs.com/package/negotiator).
+Extracted from [koa](https://www.npmjs.com/package/koa) for general use.
+
+In addition to negotiator, it allows:
+
+- Allows types as an array or arguments list, ie `(['text/html', 'application/json'])`
+ as well as `('text/html', 'application/json')`.
+- Allows type shorthands such as `json`.
+- Returns `false` when no types match
+- Treats non-existent headers as `*`
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install accepts
+```
+
+## API
+
+
+
+```js
+var accepts = require('accepts')
+```
+
+### accepts(req)
+
+Create a new `Accepts` object for the given `req`.
+
+#### .charset(charsets)
+
+Return the first accepted charset. If nothing in `charsets` is accepted,
+then `false` is returned.
+
+#### .charsets()
+
+Return the charsets that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .encoding(encodings)
+
+Return the first accepted encoding. If nothing in `encodings` is accepted,
+then `false` is returned.
+
+#### .encodings()
+
+Return the encodings that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .language(languages)
+
+Return the first accepted language. If nothing in `languages` is accepted,
+then `false` is returned.
+
+#### .languages()
+
+Return the languages that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .type(types)
+
+Return the first accepted type (and it is returned as the same text as what
+appears in the `types` array). If nothing in `types` is accepted, then `false`
+is returned.
+
+The `types` array can contain full MIME types or file extensions. Any value
+that is not a full MIME types is passed to `require('mime-types').lookup`.
+
+#### .types()
+
+Return the types that the request accepts, in the order of the client's
+preference (most preferred first).
+
+## Examples
+
+### Simple type negotiation
+
+This simple example shows how to use `accepts` to return a different typed
+respond body based on what the client wants to accept. The server lists it's
+preferences in order and will get back the best match between the client and
+server.
+
+```js
+var accepts = require('accepts')
+var http = require('http')
+
+function app (req, res) {
+ var accept = accepts(req)
+
+ // the order of this list is significant; should be server preferred order
+ switch (accept.type(['json', 'html'])) {
+ case 'json':
+ res.setHeader('Content-Type', 'application/json')
+ res.write('{"hello":"world!"}')
+ break
+ case 'html':
+ res.setHeader('Content-Type', 'text/html')
+ res.write('hello, world!')
+ break
+ default:
+ // the fallback is text/plain, so no need to specify it above
+ res.setHeader('Content-Type', 'text/plain')
+ res.write('hello, world!')
+ break
+ }
+
+ res.end()
+}
+
+http.createServer(app).listen(3000)
+```
+
+You can test this out with the cURL program:
+```sh
+curl -I -H'Accept: text/html' http://localhost:3000/
+```

+## 2.0.6
+
+Version 2.0.4 adds support for React Native by clarifying in package.json that
+the browser environment does not support Node.js domains.
+Why this is necessary, we leave as an exercise for the user.
+
+## 2.0.3
+
+Version 2.0.3 fixes a bug when adjusting the capacity of the task queue.
+
+## 2.0.1-2.02
+
+Version 2.0.1 fixes a bug in the way redirects were expressed that affected the
+function of Browserify, but which Mr would tolerate.
+
+## 2.0.0
+
+Version 2 of ASAP is a full rewrite with a few salient changes.
+First, the ASAP source is CommonJS only and designed with [Browserify][] and
+[Browserify-compatible][Mr] module loaders in mind.
+
+[Browserify]: https://github.com/substack/node-browserify
+[Mr]: https://github.com/montagejs/mr
+
+The new version has been refactored in two dimensions.
+Support for Node.js and browsers have been separated, using Browserify
+redirects and ASAP has been divided into two modules.
+The "raw" layer depends on the tasks to catch thrown exceptions and unravel
+Node.js domains.
+
+The full implementation of ASAP is loadable as `require("asap")` in both Node.js
+and browsers.
+
+The raw layer that lacks exception handling overhead is loadable as
+`require("asap/raw")`.
+The interface is the same for both layers.
+
+Tasks are no longer required to be functions, but can rather be any object that
+implements `task.call()`.
+With this feature you can recycle task objects to avoid garbage collector churn
+and avoid closures in general.
+

+# ASAP
+
+[](https://travis-ci.org/kriskowal/asap)
+
+Promise and asynchronous observer libraries, as well as hand-rolled callback
+programs and libraries, often need a mechanism to postpone the execution of a
+callback until the next available event.
+(See [Designing API’s for Asynchrony][Zalgo].)
+The `asap` function executes a task **as soon as possible** but not before it
+returns, waiting only for the completion of the current event and previously
+scheduled tasks.
+
+```javascript
+asap(function () {
+ // ...
+});
+```
+
+[Zalgo]: http://blog.izs.me/post/59142742143/designing-apis-for-asynchrony
+
+This CommonJS package provides an `asap` module that exports a function that
+executes a task function *as soon as possible*.
+
+ASAP strives to schedule events to occur before yielding for IO, reflow,
+or redrawing.
+Each event receives an independent stack, with only platform code in parent
+frames and the events run in the order they are scheduled.
+
+ASAP provides a fast event queue that will execute tasks until it is
+empty before yielding to the JavaScript engine's underlying event-loop.
+When a task gets added to a previously empty event queue, ASAP schedules a flush
+event, preferring for that event to occur before the JavaScript engine has an
+opportunity to perform IO tasks or rendering, thus making the first task and
+subsequent tasks semantically indistinguishable.
+ASAP uses a variety of techniques to preserve this invariant on different
+versions of browsers and Node.js.
+
+By design, ASAP prevents input events from being handled until the task
+queue is empty.
+If the process is busy enough, this may cause incoming connection requests to be
+dropped, and may cause existing connections to inform the sender to reduce the
+transmission rate or stall.
+ASAP allows this on the theory that, if there is enough work to do, there is no
+sense in looking for trouble.
+As a consequence, ASAP can interfere with smooth animation.
+If your task should be tied to the rendering loop, consider using
+`requestAnimationFrame` instead.
+A long sequence of tasks can also effect the long running script dialog.
+If this is a problem, you may be able to use ASAP’s cousin `setImmediate` to
+break long processes into shorter intervals and periodically allow the browser
+to breathe.
+`setImmediate` will yield for IO, reflow, and repaint events.
+It also returns a handler and can be canceled.
+For a `setImmediate` shim, consider [YuzuJS setImmediate][setImmediate].
+
+[setImmediate]: https://github.com/YuzuJS/setImmediate
+
+Take care.
+ASAP can sustain infinite recursive calls without warning.
+It will not halt from a stack overflow, and it will not consume unbounded
+memory.
+This is behaviorally equivalent to an infinite loop.
+Just as with infinite loops, you can monitor a Node.js process for this behavior
+with a heart-beat signal.
+As with infinite loops, a very small amount of caution goes a long way to
+avoiding problems.
+
+```javascript
+function loop() {
+ asap(loop);
+}
+loop();
+```
+
+In browsers, if a task throws an exception, it will not interrupt the flushing
+of high-priority tasks.
+The exception will be postponed to a later, low-priority event to avoid
+slow-downs.
+In Node.js, if a task throws an exception, ASAP will resume flushing only if—and
+only after—the error is handled by `domain.on("error")` or
+`process.on("uncaughtException")`.
+
+## Raw ASAP
+
+Checking for exceptions comes at a cost.
+The package also provides an `asap/raw` module that exports the underlying
+implementation which is faster but stalls if a task throws an exception.
+This internal version of the ASAP function does not check for errors.
+If a task does throw an error, it will stall the event queue unless you manually
+call `rawAsap.requestFlush()` before throwing the error, or any time after.
+
+In Node.js, `asap/raw` also runs all tasks outside any domain.
+If you need a task to be bound to your domain, you will have to do it manually.
+
+```js
+if (process.domain) {
+ task = process.domain.bind(task);
+}
+rawAsap(task);
+```
+
+## Tasks
+
+A task may be any object that implements `call()`.
+A function will suffice, but closures tend not to be reusable and can cause
+garbage collector churn.
+Both `asap` and `rawAsap` accept task objects to give you the option of
+recycling task objects or using higher callable object abstractions.
+See the `asap` source for an illustration.
+
+
+## Compatibility
+
+ASAP is tested on Node.js v0.10 and in a broad spectrum of web browsers.
+The following charts capture the browser test results for the most recent
+release.
+The first chart shows test results for ASAP running in the main window context.
+The second chart shows test results for ASAP running in a web worker context.
+Test results are inconclusive (grey) on browsers that do not support web
+workers.
+These data are captured automatically by [Continuous
+Integration][].

+
+
+
+
+
+## Caveats
+
+When a task is added to an empty event queue, it is not always possible to
+guarantee that the task queue will begin flushing immediately after the current
+event.
+However, once the task queue begins flushing, it will not yield until the queue
+is empty, even if the queue grows while executing tasks.
+
+The following browsers allow the use of [DOM mutation observers][] to access
+the HTML [microtask queue][], and thus begin flushing ASAP's task queue
+immediately at the end of the current event loop turn, before any rendering or
+IO:
+
+[microtask queue]: http://www.whatwg.org/specs/web-apps/current-work/multipage/webappapis.html#microtask-queue
+[DOM mutation observers]: http://dom.spec.whatwg.org/#mutation-observers
+
+- Android 4–4.3
+- Chrome 26–34
+- Firefox 14–29
+- Internet Explorer 11
+- iPad Safari 6–7.1
+- iPhone Safari 7–7.1
+- Safari 6–7
+
+In the absense of mutation observers, there are a few browsers, and situations
+like web workers in some of the above browsers, where [message channels][]
+would be a useful way to avoid falling back to timers.
+Message channels give direct access to the HTML [task queue][], so the ASAP
+task queue would flush after any already queued rendering and IO tasks, but
+without having the minimum delay imposed by timers.
+However, among these browsers, Internet Explorer 10 and Safari do not reliably
+dispatch messages, so they are not worth the trouble to implement.
+
+[message channels]: http://www.whatwg.org/specs/web-apps/current-work/multipage/web-messaging.html#message-channels
+[task queue]: http://www.whatwg.org/specs/web-apps/current-work/multipage/webappapis.html#concept-task
+
+- Internet Explorer 10
+- Safair 5.0-1
+- Opera 11-12
+
+In the absense of mutation observers, these browsers and the following browsers
+all fall back to using `setTimeout` and `setInterval` to ensure that a `flush`
+occurs.
+The implementation uses both and cancels whatever handler loses the race, since
+`setTimeout` tends to occasionally skip tasks in unisolated circumstances.
+Timers generally delay the flushing of ASAP's task queue for four milliseconds.
+
+- Firefox 3–13
+- Internet Explorer 6–10
+- iPad Safari 4.3
+- Lynx 2.8.7
+
+
+## Heritage
+
+ASAP has been factored out of the [Q][] asynchronous promise library.
+It originally had a naïve implementation in terms of `setTimeout`, but
+[Malte Ubl][NonBlocking] provided an insight that `postMessage` might be
+useful for creating a high-priority, no-delay event dispatch hack.
+Since then, Internet Explorer proposed and implemented `setImmediate`.
+Robert Katić began contributing to Q by measuring the performance of
+the internal implementation of `asap`, paying particular attention to
+error recovery.
+Domenic, Robert, and Kris Kowal collectively settled on the current strategy of
+unrolling the high-priority event queue internally regardless of what strategy
+we used to dispatch the potentially lower-priority flush event.
+Domenic went on to make ASAP cooperate with Node.js domains.
+
+[Q]: https://github.com/kriskowal/q
+[NonBlocking]: http://www.nonblocking.io/2011/06/windownexttick.html
+
+For further reading, Nicholas Zakas provided a thorough article on [The
+Case for setImmediate][NCZ].
+
+[NCZ]: http://www.nczonline.net/blog/2013/07/09/the-case-for-setimmediate/
+
+Ember’s RSVP promise implementation later [adopted][RSVP ASAP] the name ASAP but
+further developed the implentation.
+Particularly, The `MessagePort` implementation was abandoned due to interaction
+[problems with Mobile Internet Explorer][IE Problems] in favor of an
+implementation backed on the newer and more reliable DOM `MutationObserver`
+interface.
+These changes were back-ported into this library.
+
+[IE Problems]: https://github.com/cujojs/when/issues/197
+[RSVP ASAP]: https://github.com/tildeio/rsvp.js/blob/cddf7232546a9cf858524b75cde6f9edf72620a7/lib/rsvp/asap.js
+
+In addition, ASAP factored into `asap` and `asap/raw`, such that `asap` remained
+exception-safe, but `asap/raw` provided a tight kernel that could be used for
+tasks that guaranteed that they would not throw exceptions.
+This core is useful for promise implementations that capture thrown errors in
+rejected promises and do not need a second safety net.
+At the same time, the exception handling in `asap` was factored into separate
+implementations for Node.js and browsers, using the the [Browserify][Browser
+Config] `browser` property in `package.json` to instruct browser module loaders
+and bundlers, including [Browserify][], [Mr][], and [Mop][], to use the
+browser-only implementation.

+- Clarified Async's browser support (#1643)
+
+
+# v3.0.0
+
+The `async`/`await` release!
+
+There are a lot of new features and subtle breaking changes in this major version, but the biggest feature is that most Async methods return a Promise if you omit the callback, meaning you can `await` them from within an `async` function.
+
+```js
+const results = await async.mapLimit(urls, 5, async url => {
+ const resp = await fetch(url)
+ return resp.body
+})
+```
+
+## Breaking Changes
+- Most Async methods return a Promise when the final callback is omitted, making them `await`-able! (#1572)
+- We are now making heavy use of ES2015 features, this means we have dropped out-of-the-box support for Node 4 and earlier, and many old versions of browsers. (#1541, #1553)
+- In `queue`, `priorityQueue`, `cargo` and `cargoQueue`, the "event"-style methods, like `q.drain` and `q.saturated` are now methods that register a callback, rather than properties you assign a callback to. They are now of the form `q.drain(callback)`. If you do not pass a callback a Promise will be returned for the next occurrence of the event, making them `await`-able, e.g. `await q.drain()`. (#1586, #1641)
+- Calling `callback(false)` will cancel an async method, preventing further iteration and callback calls. This is useful for preventing memory leaks when you break out of an async flow by calling an outer callback. (#1064, #1542)
+- `during` and `doDuring` have been removed, and instead `whilst`, `doWhilst`, `until` and `doUntil` now have asynchronous `test` functions. (#850, #1557)
+- `limits` of less than 1 now cause an error to be thrown in queues and collection methods. (#1249, #1552)
+- `memoize` no longer memoizes errors (#1465, #1466)
+- `applyEach`/`applyEachSeries` have a simpler interface, to make them more easily type-able. It always returns a function that takes in a single callback argument. If that callback is omitted, a promise is returned, making it awaitable. (#1228, #1640)
+
+## New Features
+- Async generators are now supported in all the Collection methods. (#1560)
+- Added `cargoQueue`, a queue with both `concurrency` and `payload` size parameters. (#1567)
+- Queue objects returned from `queue` now have a `Symbol.iterator` method, meaning they can be iterated over to inspect the current list of items in the queue. (#1459, #1556)
+- A ESM-flavored `async.mjs` is included in the `async` package. This is described in the `package.json` `"module"` field, meaning it should be automatically used by Webpack and other compatible bundlers.
+

+- Fixed a stack overflow with large collections and a synchronous iterator (#1514)
+- Various small fixes/chores (#1505, #1511, #1527, #1530)
+
+# v2.6.0
+- Added missing aliases for many methods. Previously, you could not (e.g.) `require('async/find')` or use `async.anyLimit`. (#1483)
+- Improved `queue` performance. (#1448, #1454)
+- Add missing sourcemap (#1452, #1453)
+- Various doc updates (#1448, #1471, #1483)

+- `concat` improvements: it now preserves order, handles falsy values and the `iteratee` callback takes a variable number of arguments ([#1437](https://github.com/caolan/async/issues/1437), [#1436](https://github.com/caolan/async/pull/1436))
+- Fixed an issue in `queue` where there was a size discrepancy between `workersList().length` and `running()` ([#1428](https://github.com/caolan/async/issues/1428), [#1429](https://github.com/caolan/async/pull/1429))
+- Various doc fixes ([#1422](https://github.com/caolan/async/issues/1422), [#1424](https://github.com/caolan/async/pull/1424))
+
+# v2.4.1
+- Fixed a bug preventing functions wrapped with `timeout()` from being re-used. ([#1418](https://github.com/caolan/async/issues/1418), [#1419](https://github.com/caolan/async/issues/1419))
+
+# v2.4.0
+- Added `tryEach`, for running async functions in parallel, where you only expect one to succeed. ([#1365](https://github.com/caolan/async/issues/1365), [#687](https://github.com/caolan/async/issues/687))
+- Improved performance, most notably in `parallel` and `waterfall` ([#1395](https://github.com/caolan/async/issues/1395))
+- Added `queue.remove()`, for removing items in a `queue` ([#1397](https://github.com/caolan/async/issues/1397), [#1391](https://github.com/caolan/async/issues/1391))
+- Fixed using `eval`, preventing Async from running in pages with Content Security Policy ([#1404](https://github.com/caolan/async/issues/1404), [#1403](https://github.com/caolan/async/issues/1403))
+- Fixed errors thrown in an `asyncify`ed function's callback being caught by the underlying Promise ([#1408](https://github.com/caolan/async/issues/1408))

+
+# v2.3.0
+- Added support for ES2017 `async` functions. Wherever you can pass a Node-style/CPS function that uses a callback, you can also pass an `async` function. Previously, you had to wrap `async` functions with `asyncify`. The caveat is that it will only work if `async` functions are supported natively in your environment, transpiled implementations can't be detected. ([#1386](https://github.com/caolan/async/issues/1386), [#1390](https://github.com/caolan/async/issues/1390))
+- Small doc fix ([#1392](https://github.com/caolan/async/issues/1392))
+
+# v2.2.0

+
+# v2.1.5
+- Fix `auto` bug when function names collided with Array.prototype ([#1358](https://github.com/caolan/async/issues/1358))

+- Create optimized hotpath for `filter` in array case.
+
+# v2.1.2
+- Fixed a stackoverflow bug with `detect`, `some`, `every` on large inputs ([#1293](https://github.com/caolan/async/issues/1293)).
+
+# v2.1.0
+
+- `retry` and `retryable` now support an optional `errorFilter` function that determines if the `task` should retry on the error ([#1256](https://github.com/caolan/async/issues/1256), [#1261](https://github.com/caolan/async/issues/1261))
+- Optimized array iteration in `race`, `cargo`, `queue`, and `priorityQueue` ([#1253](https://github.com/caolan/async/issues/1253))
+- Added alias documentation to doc site ([#1251](https://github.com/caolan/async/issues/1251), [#1254](https://github.com/caolan/async/issues/1254))
+- Added [BootStrap scrollspy](http://getbootstrap.com/javascript/#scrollspy) to docs to highlight in the sidebar the current method being viewed ([#1289](https://github.com/caolan/async/issues/1289), [#1300](https://github.com/caolan/async/issues/1300))
+- Various minor doc fixes ([#1263](https://github.com/caolan/async/issues/1263), [#1264](https://github.com/caolan/async/issues/1264), [#1271](https://github.com/caolan/async/issues/1271), [#1278](https://github.com/caolan/async/issues/1278), [#1280](https://github.com/caolan/async/issues/1280), [#1282](https://github.com/caolan/async/issues/1282), [#1302](https://github.com/caolan/async/issues/1302))
+
+# v2.0.1
+
+- Significantly optimized all iteration based collection methods such as `each`, `map`, `filter`, etc ([#1245](https://github.com/caolan/async/issues/1245), [#1246](https://github.com/caolan/async/issues/1246), [#1247](https://github.com/caolan/async/issues/1247)).
+
+# v2.0.0
+
+Lots of changes here!
+
+First and foremost, we have a slick new [site for docs](https://caolan.github.io/async/). Special thanks to [**@hargasinski**](https://github.com/hargasinski) for his work converting our old docs to `jsdoc` format and implementing the new website. Also huge ups to [**@ivanseidel**](https://github.com/ivanseidel) for designing our new logo. It was a long process for both of these tasks, but I think these changes turned out extraordinary well.
+
+The biggest feature is modularization. You can now `require("async/series")` to only require the `series` function. Every Async library function is available this way. You still can `require("async")` to require the entire library, like you could do before.
+
+We also provide Async as a collection of ES2015 modules. You can now `import {each} from 'async-es'` or `import waterfall from 'async-es/waterfall'`. If you are using only a few Async functions, and are using a ES bundler such as Rollup, this can significantly lower your build size.
+
+Major thanks to [**@Kikobeats**](github.com/Kikobeats), [**@aearly**](github.com/aearly) and [**@megawac**](github.com/megawac) for doing the majority of the modularization work, as well as [**@jdalton**](github.com/jdalton) and [**@Rich-Harris**](github.com/Rich-Harris) for advisory work on the general modularization strategy.
+
+Another one of the general themes of the 2.0 release is standardization of what an "async" function is. We are now more strictly following the node-style continuation passing style. That is, an async function is a function that:
+
+1. Takes a variable number of arguments
+2. The last argument is always a callback
+3. The callback can accept any number of arguments
+4. The first argument passed to the callback will be treated as an error result, if the argument is truthy
+5. Any number of result arguments can be passed after the "error" argument
+6. The callback is called once and exactly once, either on the same tick or later tick of the JavaScript event loop.
+
+There were several cases where Async accepted some functions that did not strictly have these properties, most notably `auto`, `every`, `some`, `filter`, `reject` and `detect`.
+
+Another theme is performance. We have eliminated internal deferrals in all cases where they make sense. For example, in `waterfall` and `auto`, there was a `setImmediate` between each task -- these deferrals have been removed. A `setImmediate` call can add up to 1ms of delay. This might not seem like a lot, but it can add up if you are using many Async functions in the course of processing a HTTP request, for example. Nearly all asynchronous functions that do I/O already have some sort of deferral built in, so the extra deferral is unnecessary. The trade-off of this change is removing our built-in stack-overflow defense. Many synchronous callback calls in series can quickly overflow the JS call stack. If you do have a function that is sometimes synchronous (calling its callback on the same tick), and are running into stack overflows, wrap it with `async.ensureAsync()`.
+
+Another big performance win has been re-implementing `queue`, `cargo`, and `priorityQueue` with [doubly linked lists](https://en.wikipedia.org/wiki/Doubly_linked_list) instead of arrays. This has lead to queues being an order of [magnitude faster on large sets of tasks](https://github.com/caolan/async/pull/1205).
+
+## New Features
+
+- Async is now modularized. Individual functions can be `require()`d from the main package. (`require('async/auto')`) ([#984](https://github.com/caolan/async/issues/984), [#996](https://github.com/caolan/async/issues/996))
+- Async is also available as a collection of ES2015 modules in the new `async-es` package. (`import {forEachSeries} from 'async-es'`) ([#984](https://github.com/caolan/async/issues/984), [#996](https://github.com/caolan/async/issues/996))
+- Added `race`, analogous to `Promise.race()`. It will run an array of async tasks in parallel and will call its callback with the result of the first task to respond. ([#568](https://github.com/caolan/async/issues/568), [#1038](https://github.com/caolan/async/issues/1038))
+- Collection methods now accept ES2015 iterators. Maps, Sets, and anything that implements the iterator spec can now be passed directly to `each`, `map`, `parallel`, etc.. ([#579](https://github.com/caolan/async/issues/579), [#839](https://github.com/caolan/async/issues/839), [#1074](https://github.com/caolan/async/issues/1074))
+- Added `mapValues`, for mapping over the properties of an object and returning an object with the same keys. ([#1157](https://github.com/caolan/async/issues/1157), [#1177](https://github.com/caolan/async/issues/1177))
+- Added `timeout`, a wrapper for an async function that will make the task time-out after the specified time. ([#1007](https://github.com/caolan/async/issues/1007), [#1027](https://github.com/caolan/async/issues/1027))
+- Added `reflect` and `reflectAll`, analagous to [`Promise.reflect()`](http://bluebirdjs.com/docs/api/reflect.html), a wrapper for async tasks that always succeeds, by gathering results and errors into an object. ([#942](https://github.com/caolan/async/issues/942), [#1012](https://github.com/caolan/async/issues/1012), [#1095](https://github.com/caolan/async/issues/1095))
+- `constant` supports dynamic arguments -- it will now always use its last argument as the callback. ([#1016](https://github.com/caolan/async/issues/1016), [#1052](https://github.com/caolan/async/issues/1052))
+- `setImmediate` and `nextTick` now support arguments to partially apply to the deferred function, like the node-native versions do. ([#940](https://github.com/caolan/async/issues/940), [#1053](https://github.com/caolan/async/issues/1053))
+- `auto` now supports resolving cyclic dependencies using [Kahn's algorithm](https://en.wikipedia.org/wiki/Topological_sorting#Kahn.27s_algorithm) ([#1140](https://github.com/caolan/async/issues/1140)).
+- Added `autoInject`, a relative of `auto` that automatically spreads a task's dependencies as arguments to the task function. ([#608](https://github.com/caolan/async/issues/608), [#1055](https://github.com/caolan/async/issues/1055), [#1099](https://github.com/caolan/async/issues/1099), [#1100](https://github.com/caolan/async/issues/1100))
+- You can now limit the concurrency of `auto` tasks. ([#635](https://github.com/caolan/async/issues/635), [#637](https://github.com/caolan/async/issues/637))
+- Added `retryable`, a relative of `retry` that wraps an async function, making it retry when called. ([#1058](https://github.com/caolan/async/issues/1058))
+- `retry` now supports specifying a function that determines the next time interval, useful for exponential backoff, logging and other retry strategies. ([#1161](https://github.com/caolan/async/issues/1161))
+- `retry` will now pass all of the arguments the task function was resolved with to the callback ([#1231](https://github.com/caolan/async/issues/1231)).
+- Added `q.unsaturated` -- callback called when a `queue`'s number of running workers falls below a threshold. ([#868](https://github.com/caolan/async/issues/868), [#1030](https://github.com/caolan/async/issues/1030), [#1033](https://github.com/caolan/async/issues/1033), [#1034](https://github.com/caolan/async/issues/1034))
+- Added `q.error` -- a callback called whenever a `queue` task calls its callback with an error. ([#1170](https://github.com/caolan/async/issues/1170))
+- `applyEach` and `applyEachSeries` now pass results to the final callback. ([#1088](https://github.com/caolan/async/issues/1088))
+
+## Breaking changes
+
+- Calling a callback more than once is considered an error, and an error will be thrown. This had an explicit breaking change in `waterfall`. If you were relying on this behavior, you should more accurately represent your control flow as an event emitter or stream. ([#814](https://github.com/caolan/async/issues/814), [#815](https://github.com/caolan/async/issues/815), [#1048](https://github.com/caolan/async/issues/1048), [#1050](https://github.com/caolan/async/issues/1050))
+- `auto` task functions now always take the callback as the last argument. If a task has dependencies, the `results` object will be passed as the first argument. To migrate old task functions, wrap them with [`_.flip`](https://lodash.com/docs#flip) ([#1036](https://github.com/caolan/async/issues/1036), [#1042](https://github.com/caolan/async/issues/1042))
+- Internal `setImmediate` calls have been refactored away. This may make existing flows vulnerable to stack overflows if you use many synchronous functions in series. Use `ensureAsync` to work around this. ([#696](https://github.com/caolan/async/issues/696), [#704](https://github.com/caolan/async/issues/704), [#1049](https://github.com/caolan/async/issues/1049), [#1050](https://github.com/caolan/async/issues/1050))
+- `map` used to return an object when iterating over an object. `map` now always returns an array, like in other libraries. The previous object behavior has been split out into `mapValues`. ([#1157](https://github.com/caolan/async/issues/1157), [#1177](https://github.com/caolan/async/issues/1177))
+- `filter`, `reject`, `some`, `every`, `detect` and their families like `{METHOD}Series` and `{METHOD}Limit` now expect an error as the first callback argument, rather than just a simple boolean. Pass `null` as the first argument, or use `fs.access` instead of `fs.exists`. ([#118](https://github.com/caolan/async/issues/118), [#774](https://github.com/caolan/async/issues/774), [#1028](https://github.com/caolan/async/issues/1028), [#1041](https://github.com/caolan/async/issues/1041))
+- `{METHOD}` and `{METHOD}Series` are now implemented in terms of `{METHOD}Limit`. This is a major internal simplification, and is not expected to cause many problems, but it does subtly affect how functions execute internally. ([#778](https://github.com/caolan/async/issues/778), [#847](https://github.com/caolan/async/issues/847))
+- `retry`'s callback is now optional. Previously, omitting the callback would partially apply the function, meaning it could be passed directly as a task to `series` or `auto`. The partially applied "control-flow" behavior has been separated out into `retryable`. ([#1054](https://github.com/caolan/async/issues/1054), [#1058](https://github.com/caolan/async/issues/1058))
+- The test function for `whilst`, `until`, and `during` used to be passed non-error args from the iteratee function's callback, but this led to weirdness where the first call of the test function would be passed no args. We have made it so the test function is never passed extra arguments, and only the `doWhilst`, `doUntil`, and `doDuring` functions pass iteratee callback arguments to the test function ([#1217](https://github.com/caolan/async/issues/1217), [#1224](https://github.com/caolan/async/issues/1224))
+- The `q.tasks` array has been renamed `q._tasks` and is now implemented as a doubly linked list (DLL). Any code that used to interact with this array will need to be updated to either use the provided helpers or support DLLs ([#1205](https://github.com/caolan/async/issues/1205)).
+- The timing of the `q.saturated()` callback in a `queue` has been modified to better reflect when tasks pushed to the queue will start queueing. ([#724](https://github.com/caolan/async/issues/724), [#1078](https://github.com/caolan/async/issues/1078))
+- Removed `iterator` method in favour of [ES2015 iterator protocol](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Iterators_and_Generators ) which natively supports arrays ([#1237](https://github.com/caolan/async/issues/1237))
+- Dropped support for Component, Jam, SPM, and Volo ([#1175](https://github.com/caolan/async/issues/1175), #[#176](https://github.com/caolan/async/issues/176))
+
+## Bug Fixes
+
+- Improved handling of no dependency cases in `auto` & `autoInject` ([#1147](https://github.com/caolan/async/issues/1147)).
+- Fixed a bug where the callback generated by `asyncify` with `Promises` could resolve twice ([#1197](https://github.com/caolan/async/issues/1197)).
+- Fixed several documented optional callbacks not actually being optional ([#1223](https://github.com/caolan/async/issues/1223)).
+
+## Other
+
+- Added `someSeries` and `everySeries` for symmetry, as well as a complete set of `any`/`anyLimit`/`anySeries` and `all`/`/allLmit`/`allSeries` aliases.
+- Added `find` as an alias for `detect. (as well as `findLimit` and `findSeries`).
+- Various doc fixes ([#1005](https://github.com/caolan/async/issues/1005), [#1008](https://github.com/caolan/async/issues/1008), [#1010](https://github.com/caolan/async/issues/1010), [#1015](https://github.com/caolan/async/issues/1015), [#1021](https://github.com/caolan/async/issues/1021), [#1037](https://github.com/caolan/async/issues/1037), [#1039](https://github.com/caolan/async/issues/1039), [#1051](https://github.com/caolan/async/issues/1051), [#1102](https://github.com/caolan/async/issues/1102), [#1107](https://github.com/caolan/async/issues/1107), [#1121](https://github.com/caolan/async/issues/1121), [#1123](https://github.com/caolan/async/issues/1123), [#1129](https://github.com/caolan/async/issues/1129), [#1135](https://github.com/caolan/async/issues/1135), [#1138](https://github.com/caolan/async/issues/1138), [#1141](https://github.com/caolan/async/issues/1141), [#1153](https://github.com/caolan/async/issues/1153), [#1216](https://github.com/caolan/async/issues/1216), [#1217](https://github.com/caolan/async/issues/1217), [#1232](https://github.com/caolan/async/issues/1232), [#1233](https://github.com/caolan/async/issues/1233), [#1236](https://github.com/caolan/async/issues/1236), [#1238](https://github.com/caolan/async/issues/1238))

+
+- Added `transform`, analogous to [`_.transform`](http://lodash.com/docs#transform) ([#892](https://github.com/caolan/async/issues/892))
+- `map` now returns an object when an object is passed in, rather than array with non-numeric keys. `map` will begin always returning an array with numeric indexes in the next major release. ([#873](https://github.com/caolan/async/issues/873))
+- `auto` now accepts an optional `concurrency` argument to limit the number o. running tasks ([#637](https://github.com/caolan/async/issues/637))

+- Code simplifications and optimizations aplenty ([diff](https://github.com/caolan/async/compare/v1.3.0...v1.4.0))
+
+
+# v1.3.0
+
+New Features:
+- Added `constant`
+- Added `asyncify`/`wrapSync` for making sync functions work with callbacks. ([#671](https://github.com/caolan/async/issues/671), [#806](https://github.com/caolan/async/issues/806))

+- `retry` now accepts an `interval` parameter to specify a delay between retries. ([#793](https://github.com/caolan/async/issues/793))
+- `async` should work better in Web Workers due to better `root` detection ([#804](https://github.com/caolan/async/issues/804))
+- Callbacks are now optional in `whilst`, `doWhilst`, `until`, and `doUntil` ([#642](https://github.com/caolan/async/issues/642))

+- Various doc fixes ([#790](https://github.com/caolan/async/issues/790), [#794](https://github.com/caolan/async/issues/794))
+
+Bug Fixes:
+- `cargo` now exposes the `payload` size, and `cargo.payload` can be changed on the fly after the `cargo` is created. ([#740](https://github.com/caolan/async/issues/740), [#744](https://github.com/caolan/async/issues/744), [#783](https://github.com/caolan/async/issues/783))
+
+
+# v1.2.1
+
+Bug Fix:
+
+- Small regression with synchronous iterator behavior in `eachSeries` with a 1-element array. Before 1.1.0, `eachSeries`'s callback was called on the same tick, which this patch restores. In 2.0.0, it will be called on the next tick. ([#782](https://github.com/caolan/async/issues/782))
+
+
+# v1.2.0
+
+New Features:
+
+- Added `timesLimit` ([#743](https://github.com/caolan/async/issues/743))
+- `concurrency` can be changed after initialization in `queue` by setting `q.concurrency`. The new concurrency will be reflected the next time a task is processed. ([#747](https://github.com/caolan/async/issues/747), [#772](https://github.com/caolan/async/issues/772))
+
+Bug Fixes:
+

+
+
+# v1.1.1
+

+
+
+# v1.1.0
+
+New Features:
+
+- `cargo` now supports all of the same methods and event callbacks as `queue`.
+- Added `ensureAsync` - A wrapper that ensures an async function calls its callback on a later tick. ([#769](https://github.com/caolan/async/issues/769))
+- Optimized `map`, `eachOf`, and `waterfall` families of functions
+- Passing a `null` or `undefined` array to `map`, `each`, `parallel` and families will be treated as an empty array ([#667](https://github.com/caolan/async/issues/667)).
+- The callback is now optional for the composed results of `compose` and `seq`. ([#618](https://github.com/caolan/async/issues/618))
+- Reduced file size by 4kb, (minified version by 1kb)
+- Added code coverage through `nyc` and `coveralls` ([#768](https://github.com/caolan/async/issues/768))
+
+Bug Fixes:
+
+- `forever` will no longer stack overflow with a synchronous iterator ([#622](https://github.com/caolan/async/issues/622))
+- `eachLimit` and other limit functions will stop iterating once an error occurs ([#754](https://github.com/caolan/async/issues/754))
+- Always pass `null` in callbacks when there is no error ([#439](https://github.com/caolan/async/issues/439))
+- Ensure proper conditions when calling `drain()` after pushing an empty data set to a queue ([#668](https://github.com/caolan/async/issues/668))
+- `each` and family will properly handle an empty array ([#578](https://github.com/caolan/async/issues/578))
+- `eachSeries` and family will finish if the underlying array is modified during execution ([#557](https://github.com/caolan/async/issues/557))
+- `queue` will throw if a non-function is passed to `q.push()` ([#593](https://github.com/caolan/async/issues/593))
+- Doc fixes ([#629](https://github.com/caolan/async/issues/629), [#766](https://github.com/caolan/async/issues/766))
+
+
+# v1.0.0
+
+No known breaking changes, we are simply complying with semver from here on out.
+
+Changes:
+
+- Start using a changelog!
+- Add `forEachOf` for iterating over Objects (or to iterate Arrays with indexes available) ([#168](https://github.com/caolan/async/issues/168) [#704](https://github.com/caolan/async/issues/704) [#321](https://github.com/caolan/async/issues/321))

+- Fix unneeded iteration in `queue.resume()` ([#758](https://github.com/caolan/async/issues/758))
+- Guard against timer mocking overriding `setImmediate` ([#609](https://github.com/caolan/async/issues/609) [#611](https://github.com/caolan/async/issues/611))
+- Miscellaneous doc fixes ([#542](https://github.com/caolan/async/issues/542) [#596](https://github.com/caolan/async/issues/596) [#615](https://github.com/caolan/async/issues/615) [#628](https://github.com/caolan/async/issues/628) [#631](https://github.com/caolan/async/issues/631) [#690](https://github.com/caolan/async/issues/690) [#729](https://github.com/caolan/async/issues/729))
+- Use single noop function internally ([#546](https://github.com/caolan/async/issues/546))

+Async is a utility module which provides straight-forward, powerful functions for working with [asynchronous JavaScript](http://caolan.github.io/async/v3/global.html). Although originally designed for use with [Node.js](https://nodejs.org/) and installable via `npm i async`, it can also be used directly in the browser. A ESM/MJS version is included in the main `async` package that should automatically be used with compatible bundlers such as Webpack and Rollup.
+
+A pure ESM version of Async is available as [`async-es`](https://www.npmjs.com/package/async-es).

+```javascript
+// for use with Node-style callbacks...

+var obj = {dev: "/dev.json", test: "/test.json", prod: "/prod.json"};
+var configs = {};
+
+async.forEachOf(obj, (value, key, callback) => {

+/**
+ * A dependency-injected version of the [async.auto]{@link module:ControlFlow.auto} function. Dependent
+ * tasks are specified as parameters to the function, after the usual callback
+ * parameter, with the parameter names matching the names of the tasks it
+ * depends on. This can provide even more readable task graphs which can be
+ * easier to maintain.
+ *
+ * If a final callback is specified, the task results are similarly injected,
+ * specified as named parameters after the initial error parameter.
+ *
+ * The autoInject function is purely syntactic sugar and its semantics are
+ * otherwise equivalent to [async.auto]{@link module:ControlFlow.auto}.
+ *
+ * @name autoInject
+ * @static
+ * @memberOf module:ControlFlow
+ * @method
+ * @see [async.auto]{@link module:ControlFlow.auto}
+ * @category Control Flow
+ * @param {Object} tasks - An object, each of whose properties is an {@link AsyncFunction} of
+ * the form 'func([dependencies...], callback). The object's key of a property
+ * serves as the name of the task defined by that property, i.e. can be used
+ * when specifying requirements for other tasks.
+ * * The `callback` parameter is a `callback(err, result)` which must be called
+ * when finished, passing an `error` (which can be `null`) and the result of
+ * the function's execution. The remaining parameters name other tasks on
+ * which the task is dependent, and the results from those tasks are the
+ * arguments of those parameters.
+ * @param {Function} [callback] - An optional callback which is called when all
+ * the tasks have been completed. It receives the `err` argument if any `tasks`
+ * pass an error to their callback, and a `results` object with any completed
+ * task results, similar to `auto`.
+ * @returns {Promise} a promise, if no callback is passed
+ * @example
+ *
+ * // The example from `auto` can be rewritten as follows:
+ * async.autoInject({
+ * get_data: function(callback) {
+ * // async code to get some data
+ * callback(null, 'data', 'converted to array');
+ * },
+ * make_folder: function(callback) {
+ * // async code to create a directory to store a file in
+ * // this is run at the same time as getting the data
+ * callback(null, 'folder');
+ * },
+ * write_file: function(get_data, make_folder, callback) {
+ * // once there is some data and the directory exists,
+ * // write the data to a file in the directory
+ * callback(null, 'filename');
+ * },
+ * email_link: function(write_file, callback) {
+ * // once the file is written let's email a link to it...
+ * // write_file contains the filename returned by write_file.
+ * callback(null, {'file':write_file, 'email':'user@example.com'});
+ * }
+ * }, function(err, results) {
+ * console.log('err = ', err);
+ * console.log('email_link = ', results.email_link);
+ * });
+ *
+ * // If you are using a JS minifier that mangles parameter names, `autoInject`
+ * // will not work with plain functions, since the parameter names will be
+ * // collapsed to a single letter identifier. To work around this, you can
+ * // explicitly specify the names of the parameters your task function needs
+ * // in an array, similar to Angular.js dependency injection.
+ *
+ * // This still has an advantage over plain `auto`, since the results a task
+ * // depends on are still spread into arguments.
+ * async.autoInject({
+ * //...
+ * write_file: ['get_data', 'make_folder', function(get_data, make_folder, callback) {
+ * callback(null, 'filename');
+ * }],
+ * email_link: ['write_file', function(write_file, callback) {
+ * callback(null, {'file':write_file, 'email':'user@example.com'});
+ * }]

+ * when specifying requirements for other tasks.
+ * * The `callback` parameter is a `callback(err, result)` which must be called
+ * when finished, passing an `error` (which can be `null`) and the result of
+ * the function's execution. The remaining parameters name other tasks on
+ * which the task is dependent, and the results from those tasks are the
+ * arguments of those parameters.
+ * @param {Function} [callback] - An optional callback which is called when all
+ * the tasks have been completed. It receives the `err` argument if any `tasks`
+ * pass an error to their callback, and a `results` object with any completed
+ * task results, similar to `auto`.
+ * @returns {Promise} a promise, if no callback is passed
+ * @example
+ *
+ * // The example from `auto` can be rewritten as follows:
+ * async.autoInject({
+ * get_data: function(callback) {
+ * // async code to get some data
+ * callback(null, 'data', 'converted to array');
+ * },
+ * make_folder: function(callback) {
+ * // async code to create a directory to store a file in
+ * // this is run at the same time as getting the data
+ * callback(null, 'folder');
+ * },
+ * write_file: function(get_data, make_folder, callback) {
+ * // once there is some data and the directory exists,
+ * // write the data to a file in the directory
+ * callback(null, 'filename');
+ * },
+ * email_link: function(write_file, callback) {
+ * // once the file is written let's email a link to it...
+ * // write_file contains the filename returned by write_file.
+ * callback(null, {'file':write_file, 'email':'user@example.com'});
+ * }
+ * }, function(err, results) {
+ * console.log('err = ', err);
+ * console.log('email_link = ', results.email_link);
+ * });
+ *
+ * // If you are using a JS minifier that mangles parameter names, `autoInject`
+ * // will not work with plain functions, since the parameter names will be
+ * // collapsed to a single letter identifier. To work around this, you can
+ * // explicitly specify the names of the parameters your task function needs
+ * // in an array, similar to Angular.js dependency injection.
+ *
+ * // This still has an advantage over plain `auto`, since the results a task
+ * // depends on are still spread into arguments.
+ * async.autoInject({
+ * //...
+ * write_file: ['get_data', 'make_folder', function(get_data, make_folder, callback) {

+ /**
+ * An "async function" in the context of Async is an asynchronous function with
+ * a variable number of parameters, with the final parameter being a callback.
+ * (`function (arg1, arg2, ..., callback) {}`)
+ * The final callback is of the form `callback(err, results...)`, which must be
+ * called once the function is completed. The callback should be called with a
+ * Error as its first argument to signal that an error occurred.
+ * Otherwise, if no error occurred, it should be called with `null` as the first
+ * argument, and any additional `result` arguments that may apply, to signal
+ * successful completion.
+ * The callback must be called exactly once, ideally on a later tick of the
+ * JavaScript event loop.
+ *
+ * This type of function is also referred to as a "Node-style async function",
+ * or a "continuation passing-style function" (CPS). Most of the methods of this
+ * library are themselves CPS/Node-style async functions, or functions that
+ * return CPS/Node-style async functions.
+ *
+ * Wherever we accept a Node-style async function, we also directly accept an
+ * [ES2017 `async` function]{@link https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/async_function}.
+ * In this case, the `async` function will not be passed a final callback
+ * argument, and any thrown error will be used as the `err` argument of the
+ * implicit callback, and the return value will be used as the `result` value.
+ * (i.e. a `rejected` of the returned Promise becomes the `err` callback
+ * argument, and a `resolved` value becomes the `result`.)
+ *
+ * Note, due to JavaScript limitations, we can only detect native `async`
+ * functions and not transpilied implementations.
+ * Your environment must have `async`/`await` support for this to work.
+ * (e.g. Node > v7.6, or a recent version of a modern browser).
+ * If you are using `async` functions through a transpiler (e.g. Babel), you
+ * must still wrap the function with [asyncify]{@link module:Utils.asyncify},
+ * because the `async function` will be compiled to an ordinary function that
+ * returns a promise.
+ *
+ * @typedef {Function} AsyncFunction

+ * Take a sync function and make it async, passing its return value to a

+ * * The `callback` parameter is a `callback(err, result)` which must be called

+ * An "async function" in the context of Async is an asynchronous function with

+ * (`function (arg1, arg2, ..., callback) {}`)
+ * The final callback is of the form `callback(err, results...)`, which must be
+ * called once the function is completed. The callback should be called with a
+ * Error as its first argument to signal that an error occurred.
+ * Otherwise, if no error occurred, it should be called with `null` as the first
+ * argument, and any additional `result` arguments that may apply, to signal
+ * successful completion.
+ * The callback must be called exactly once, ideally on a later tick of the
+ * JavaScript event loop.
+ *
+ * This type of function is also referred to as a "Node-style async function",
+ * or a "continuation passing-style function" (CPS). Most of the methods of this
+ * library are themselves CPS/Node-style async functions, or functions that
+ * return CPS/Node-style async functions.

+ * Wherever we accept a Node-style async function, we also directly accept an
+ * [ES2017 `async` function]{@link https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/async_function}.
+ * In this case, the `async` function will not be passed a final callback
+ * argument, and any thrown error will be used as the `err` argument of the
+ * implicit callback, and the return value will be used as the `result` value.
+ * (i.e. a `rejected` of the returned Promise becomes the `err` callback
+ * argument, and a `resolved` value becomes the `result`.)
+ *
+ * Note, due to JavaScript limitations, we can only detect native `async`
+ * functions and not transpilied implementations.
+ * Your environment must have `async`/`await` support for this to work.
+ * (e.g. Node > v7.6, or a recent version of a modern browser).
+ * If you are using `async` functions through a transpiler (e.g. Babel), you
+ * must still wrap the function with [asyncify]{@link module:Utils.asyncify},
+ * because the `async function` will be compiled to an ordinary function that
+ * returns a promise.

+ * Reduces `coll` into a single value using an async `iteratee` to return each

+ *
+ * For performance reasons, it may make sense to split a call to this function
+ * into a parallel map, and then use the normal `Array.prototype.reduce` on the
+ * results. This function is for situations where each step in the reduction
+ * needs to be async; if you can get the data before reducing it, then it's
+ * probably a good idea to do so.

+ * @param {Array|Iterable|AsyncIterable|Object} coll - A collection to iterate over.
+ * @param {*} memo - The initial state of the reduction.
+ * @param {AsyncFunction} iteratee - A function applied to each item in the

+ * The `iteratee` should complete with the next state of the reduction.
+ * If the iteratee completes with an error, the reduction is stopped and the
+ * main `callback` is immediately called with the error.

+/**
+ * An "async function" in the context of Async is an asynchronous function with
+ * a variable number of parameters, with the final parameter being a callback.
+ * (`function (arg1, arg2, ..., callback) {}`)
+ * The final callback is of the form `callback(err, results...)`, which must be
+ * called once the function is completed. The callback should be called with a
+ * Error as its first argument to signal that an error occurred.
+ * Otherwise, if no error occurred, it should be called with `null` as the first
+ * argument, and any additional `result` arguments that may apply, to signal
+ * successful completion.
+ * The callback must be called exactly once, ideally on a later tick of the
+ * JavaScript event loop.
+ *
+ * This type of function is also referred to as a "Node-style async function",
+ * or a "continuation passing-style function" (CPS). Most of the methods of this
+ * library are themselves CPS/Node-style async functions, or functions that
+ * return CPS/Node-style async functions.

+ * Wherever we accept a Node-style async function, we also directly accept an
+ * [ES2017 `async` function]{@link https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/async_function}.
+ * In this case, the `async` function will not be passed a final callback
+ * argument, and any thrown error will be used as the `err` argument of the
+ * implicit callback, and the return value will be used as the `result` value.
+ * (i.e. a `rejected` of the returned Promise becomes the `err` callback
+ * argument, and a `resolved` value becomes the `result`.)
+ *
+ * Note, due to JavaScript limitations, we can only detect native `async`
+ * functions and not transpilied implementations.
+ * Your environment must have `async`/`await` support for this to work.
+ * (e.g. Node > v7.6, or a recent version of a modern browser).
+ * If you are using `async` functions through a transpiler (e.g. Babel), you
+ * must still wrap the function with [asyncify]{@link module:Utils.asyncify},
+ * because the `async function` will be compiled to an ordinary function that
+ * returns a promise.

+/**
+ * Reduces `coll` into a single value using an async `iteratee` to return each
+ * successive step. `memo` is the initial state of the reduction. This function
+ * only operates in series.
+ *
+ * For performance reasons, it may make sense to split a call to this function
+ * into a parallel map, and then use the normal `Array.prototype.reduce` on the
+ * results. This function is for situations where each step in the reduction
+ * needs to be async; if you can get the data before reducing it, then it's
+ * probably a good idea to do so.
+ *
+ * @name reduce
+ * @static
+ * @memberOf module:Collections
+ * @method
+ * @alias inject
+ * @alias foldl
+ * @category Collection
+ * @param {Array|Iterable|AsyncIterable|Object} coll - A collection to iterate over.
+ * @param {*} memo - The initial state of the reduction.
+ * @param {AsyncFunction} iteratee - A function applied to each item in the
+ * array to produce the next step in the reduction.
+ * The `iteratee` should complete with the next state of the reduction.
+ * If the iteratee completes with an error, the reduction is stopped and the
+ * main `callback` is immediately called with the error.
+ * Invoked with (memo, item, callback).
+ * @param {Function} [callback] - A callback which is called after all the
+ * `iteratee` functions have finished. Result is the reduced value. Invoked with
+ * (err, result).
+ * @returns {Promise} a promise, if no callback is passed
+ * @example
+ *
+ * // file1.txt is a file that is 1000 bytes in size
+ * // file2.txt is a file that is 2000 bytes in size
+ * // file3.txt is a file that is 3000 bytes in size
+ * // file4.txt does not exist
+ *
+ * const fileList = ['file1.txt','file2.txt','file3.txt'];
+ * const withMissingFileList = ['file1.txt','file2.txt','file3.txt', 'file4.txt'];

+AsyncKit provides harness for `parallel` and `serial` iterators over list of items represented by arrays or objects.
+Optionally it accepts abort function (should be synchronously return by iterator for each item), and terminates left over jobs upon an error event. For specific iteration order built-in (`ascending` and `descending`) and custom sort helpers also supported, via `asynckit.serialOrdered` method.
+
+It ensures async operations to keep behavior more stable and prevent `Maximum call stack size exceeded` errors, from sync iterators.

+
+
+## Install
+
+```sh
+$ npm install --save asynckit
+```
+
+## Examples
+
+### Parallel Jobs
+
+Runs iterator over provided array in parallel. Stores output in the `result` array,
+on the matching positions. In unlikely event of an error from one of the jobs,
+will terminate rest of the active jobs (if abort function is provided)
+and return error along with salvaged data to the main callback function.
+
+#### Input Array
+
+```javascript
+var parallel = require('asynckit').parallel
+ , assert = require('assert')
+ ;
+
+var source = [ 1, 1, 4, 16, 64, 32, 8, 2 ]
+ , expectedResult = [ 2, 2, 8, 32, 128, 64, 16, 4 ]
+ , expectedTarget = [ 1, 1, 2, 4, 8, 16, 32, 64 ]
+ , target = []
+ ;
+
+parallel(source, asyncJob, function(err, result)
+{
+ assert.deepEqual(result, expectedResult);
+ assert.deepEqual(target, expectedTarget);
+});
+
+// async job accepts one element from the array
+// and a callback function
+function asyncJob(item, cb)
+{
+ // different delays (in ms) per item
+ var delay = item * 25;
+
+ // pretend different jobs take different time to finish
+ // and not in consequential order
+ var timeoutId = setTimeout(function() {
+ target.push(item);
+ cb(null, item * 2);
+ }, delay);
+
+ // allow to cancel "leftover" jobs upon error
+ // return function, invoking of which will abort this job
+ return clearTimeout.bind(null, timeoutId);
+}
+```
+
+More examples could be found in [test/test-parallel-array.js](test/test-parallel-array.js).
+
+#### Input Object
+
+Also it supports named jobs, listed via object.
+
+```javascript
+var parallel = require('asynckit/parallel')
+ , assert = require('assert')
+ ;
+
+var source = { first: 1, one: 1, four: 4, sixteen: 16, sixtyFour: 64, thirtyTwo: 32, eight: 8, two: 2 }
+ , expectedResult = { first: 2, one: 2, four: 8, sixteen: 32, sixtyFour: 128, thirtyTwo: 64, eight: 16, two: 4 }
+ , expectedTarget = [ 1, 1, 2, 4, 8, 16, 32, 64 ]
+ , expectedKeys = [ 'first', 'one', 'two', 'four', 'eight', 'sixteen', 'thirtyTwo', 'sixtyFour' ]
+ , target = []
+ , keys = []
+ ;
+
+parallel(source, asyncJob, function(err, result)
+{
+ assert.deepEqual(result, expectedResult);
+ assert.deepEqual(target, expectedTarget);
+ assert.deepEqual(keys, expectedKeys);
+});
+
+// supports full value, key, callback (shortcut) interface
+function asyncJob(item, key, cb)
+{
+ // different delays (in ms) per item
+ var delay = item * 25;
+
+ // pretend different jobs take different time to finish
+ // and not in consequential order
+ var timeoutId = setTimeout(function() {
+ keys.push(key);
+ target.push(item);
+ cb(null, item * 2);
+ }, delay);
+
+ // allow to cancel "leftover" jobs upon error
+ // return function, invoking of which will abort this job
+ return clearTimeout.bind(null, timeoutId);
+}
+```
+
+More examples could be found in [test/test-parallel-object.js](test/test-parallel-object.js).
+
+### Serial Jobs
+
+Runs iterator over provided array sequentially. Stores output in the `result` array,
+on the matching positions. In unlikely event of an error from one of the jobs,
+will not proceed to the rest of the items in the list
+and return error along with salvaged data to the main callback function.
+
+#### Input Array
+
+```javascript
+var serial = require('asynckit/serial')
+ , assert = require('assert')
+ ;
+
+var source = [ 1, 1, 4, 16, 64, 32, 8, 2 ]
+ , expectedResult = [ 2, 2, 8, 32, 128, 64, 16, 4 ]
+ , expectedTarget = [ 0, 1, 2, 3, 4, 5, 6, 7 ]
+ , target = []
+ ;
+
+serial(source, asyncJob, function(err, result)
+{
+ assert.deepEqual(result, expectedResult);
+ assert.deepEqual(target, expectedTarget);
+});
+
+// extended interface (item, key, callback)
+// also supported for arrays
+function asyncJob(item, key, cb)
+{
+ target.push(key);
+
+ // it will be automatically made async
+ // even it iterator "returns" in the same event loop
+ cb(null, item * 2);
+}
+```
+
+More examples could be found in [test/test-serial-array.js](test/test-serial-array.js).
+
+#### Input Object
+
+Also it supports named jobs, listed via object.
+
+```javascript
+var serial = require('asynckit').serial
+ , assert = require('assert')
+ ;
+
+var source = [ 1, 1, 4, 16, 64, 32, 8, 2 ]
+ , expectedResult = [ 2, 2, 8, 32, 128, 64, 16, 4 ]
+ , expectedTarget = [ 0, 1, 2, 3, 4, 5, 6, 7 ]
+ , target = []
+ ;
+
+var source = { first: 1, one: 1, four: 4, sixteen: 16, sixtyFour: 64, thirtyTwo: 32, eight: 8, two: 2 }
+ , expectedResult = { first: 2, one: 2, four: 8, sixteen: 32, sixtyFour: 128, thirtyTwo: 64, eight: 16, two: 4 }
+ , expectedTarget = [ 1, 1, 4, 16, 64, 32, 8, 2 ]
+ , target = []
+ ;
+
+
+serial(source, asyncJob, function(err, result)
+{
+ assert.deepEqual(result, expectedResult);
+ assert.deepEqual(target, expectedTarget);
+});
+
+// shortcut interface (item, callback)
+// works for object as well as for the arrays
+function asyncJob(item, cb)
+{
+ target.push(item);
+
+ // it will be automatically made async
+ // even it iterator "returns" in the same event loop
+ cb(null, item * 2);
+}
+```
+
+More examples could be found in [test/test-serial-object.js](test/test-serial-object.js).
+
+_Note: Since _object_ is an _unordered_ collection of properties,
+it may produce unexpected results with sequential iterations.
+Whenever order of the jobs' execution is important please use `serialOrdered` method._
+
+### Ordered Serial Iterations
+
+TBD
+
+For example [compare-property](compare-property) package.
+
+### Streaming interface
+
+TBD
