deep-is
==========
Node's `assert.deepEqual() algorithm` as a standalone module. Exactly like
[deep-equal](https://github.com/substack/node-deep-equal) except for the fact that `deepEqual(NaN, NaN) === true`.
This module is around [5 times faster](https://gist.github.com/2790507)
than wrapping `assert.deepEqual()` in a `try/catch`.
[![browser support](http://ci.testling.com/thlorenz/deep-is.png)](http://ci.testling.com/thlorenz/deep-is)
[![build status](https://secure.travis-ci.org/thlorenz/deep-is.png)](http://travis-ci.org/thlorenz/deep-is)
example
=======
``` js
var equal = require('deep-is');
console.dir([
equal(
{ a : [ 2, 3 ], b : [ 4 ] },
{ a : [ 2, 3 ], b : [ 4 ] }
),
equal(
{ x : 5, y : [6] },
{ x : 5, y : 6 }
)
]);
```
methods
=======
var deepIs = require('deep-is')
deepIs(a, b)
---------------
Compare objects `a` and `b`, returning whether they are equal according to a
recursive equality algorithm.
install
=======
With [npm](http://npmjs.org) do:

## 2.0.1
- fix(types): incorrect return type on `size()`
## 2.0.0
- fix!: `push` & `unshift` now accept `undefined` values to match behaviour of `Array` (fixes #25) (#35)
- This is only a **BREAKING** change if you are currently expecting `push(undefined)` and `unshift(undefined)` to do
nothing - the new behaviour now correctly adds undefined values to the queue.
- **Note**: behaviour of `push()` & `unshift()` (no arguments) remains unchanged (nothing gets added to the queue).
- **Note**: If you need to differentiate between `undefined` values in the queue and the return value of `pop()` then
check the queue `.length` before popping.
- fix: incorrect methods in types definition file
## 1.5.1
- perf: minor performance tweak when growing queue size (#29)
## 1.5.0 ## 1.5.0
- feat: adds capacity option for circular buffers (#27) - feat: adds capacity option for circular buffers (#27)

Denque is a well tested, extremely fast and lightweight [double-ended queue](http://en.wikipedia.org/wiki/Double-ended_queue) Extremely fast and lightweight [double-ended queue](http://en.wikipedia.org/wiki/Double-ended_queue) implementation with zero dependencies.
implementation with zero dependencies and includes TypeScript types.
Double-ended queues can also be used as a: Double-ended queues can also be used as a:
- [Stack](http://en.wikipedia.org/wiki/Stack_\(abstract_data_type\)) - [Stack](http://en.wikipedia.org/wiki/Stack_\(abstract_data_type\))
- [Queue](http://en.wikipedia.org/wiki/Queue_\(data_structure\)) - [Queue](http://en.wikipedia.org/wiki/Queue_\(data_structure\))
This implementation is currently the fastest available, even faster than `double-ended-queue`, see the [benchmarks](https://docs.page/invertase/denque/benchmarks). This implementation is currently the fastest available, even faster than `double-ended-queue`, see the [benchmarks](#benchmarks)
Every queue operation is done at a constant `O(1)` - including random access from `.peekAt(index)`. Every queue operation is done at a constant `O(1)` - including random access from `.peekAt(index)`.

#### `new Denque()` -> `Denque`
Creates an empty double-ended queue with initial capacity of 4.
```js ```js
const Denque = require("denque"); var denque = new Denque();
denque.push(1);
denque.push(2);
denque.push(3);
denque.shift(); //1
denque.pop(); //3
```
const denque = new Denque([1,2,3,4]); <hr>
#### `new Denque(Array items)` -> `Denque`
Creates a double-ended queue from `items`.
```js
var denque = new Denque([1,2,3,4]);
denque.shift(); // 1 denque.shift(); // 1
denque.pop(); // 4 denque.pop(); // 4
``` ```
<hr>
See the [API reference documentation](https://docs.page/invertase/denque/api) for more examples.
--- #### `push(item)` -> `int`
## Who's using it? Push an item to the back of this queue. Returns the amount of items currently in the queue after the operation.
- [Kafka Node.js client](https://www.npmjs.com/package/kafka-node) ```js
- [MariaDB Node.js client](https://www.npmjs.com/package/mariadb) var denque = new Denque();
- [MongoDB Node.js client](https://www.npmjs.com/package/mongodb) denque.push(1);
- [MySQL Node.js client](https://www.npmjs.com/package/mysql2) denque.pop(); // 1
- [Redis Node.js clients](https://www.npmjs.com/package/redis) denque.push(2);
denque.push(3);
denque.shift(); // 2
denque.shift(); // 3
```
... and [many more](https://www.npmjs.com/browse/depended/denque). <hr>
#### `unshift(item)` -> `int`
--- Unshift an item to the front of this queue. Returns the amount of items currently in the queue after the operation.
```js
var denque = new Denque([2,3]);
denque.unshift(1);
denque.toString(); // "1,2,3"
denque.unshift(-2);
denque.toString(); // "-2,-1,0,1,2,3"
```
<hr>
#### `pop()` -> `dynamic`
Pop off the item at the back of this queue.
Note: The item will be removed from the queue. If you simply want to see what's at the back of the queue use [`peekBack()`](#peekback---dynamic) or [`.peekAt(-1)`](#peekAtint-index---dynamic).
If the queue is empty, `undefined` is returned. If you need to differentiate between `undefined` values in the queue and `pop()` return value -
check the queue `.length` before popping.
```js
var denque = new Denque([1,2,3]);
denque.pop(); // 3
denque.pop(); // 2
denque.pop(); // 1
denque.pop(); // undefined
```
**Aliases:** `removeBack`
<hr>
#### `shift()` -> `dynamic`
Shifts off the item at the front of this queue.
Note: The item will be removed from the queue. If you simply want to see what's at the front of the queue use [`peekFront()`](#peekfront---dynamic) or [`.peekAt(0)`](#peekAtint-index---dynamic).
If the queue is empty, `undefined` is returned. If you need to differentiate between `undefined` values in the queue and `shift()` return value -
check the queue `.length` before shifting.
```js
var denque = new Denque([1,2,3]);
denque.shift(); // 1
denque.shift(); // 2
denque.shift(); // 3
denque.shift(); // undefined
```
<hr>
#### `toArray()` -> `Array`
Returns the items in the queue as an array. Starting from the item in the front of the queue and ending to the item at the back of the queue.
```js
var denque = new Denque([1,2,3]);
denque.push(4);
denque.unshift(0);
denque.toArray(); // [0,1,2,3,4]
```
<hr>
#### `peekBack()` -> `dynamic`
Returns the item that is at the back of this queue without removing it.
If the queue is empty, `undefined` is returned.
```js
var denque = new Denque([1,2,3]);
denque.push(4);
denque.peekBack(); // 4
```
<hr>
#### `peekFront()` -> `dynamic`
Returns the item that is at the front of this queue without removing it.
If the queue is empty, `undefined` is returned.
```js
var denque = new Denque([1,2,3]);
denque.push(4);
denque.peekFront(); // 1
```
<hr>
#### `peekAt(int index)` -> `dynamic`
Returns the item that is at the given `index` of this queue without removing it.
## License The index is zero-based, so `.peekAt(0)` will return the item that is at the front, `.peekAt(1)` will return
the item that comes after and so on.
- See [LICENSE](/LICENSE) The index can be negative to read items at the back of the queue. `.peekAt(-1)` returns the item that is at the back of the queue,
`.peekAt(-2)` will return the item that comes before and so on.
Returns `undefined` if `index` is not a valid index into the queue.
```js
var denque = new Denque([1,2,3]);
denque.peekAt(0); //1
denque.peekAt(1); //2
denque.peekAt(2); //3
denque.peekAt(-1); // 3
denque.peekAt(-2); // 2
denque.peekAt(-3); // 1
```
**Note**: The implementation has O(1) random access using `.peekAt()`.
**Aliases:** `get`
<hr>
#### `remove(int index, int count)` -> `array`
Remove number of items from the specified index from the list.
Returns array of removed items.
Returns undefined if the list is empty.
```js
var denque = new Denque([1,2,3,4,5,6,7]);
denque.remove(0,3); //[1,2,3]
denque.remove(1,2); //[5,6]
var denque1 = new Denque([1,2,3,4,5,6,7]);
denque1.remove(4, 100); //[5,6,7]
```
<hr>
#### `removeOne(int index)` -> `dynamic`
Remove and return the item at the specified index from the list.
Returns undefined if the list is empty.
```js
var denque = new Denque([1,2,3,4,5,6,7]);
denque.removeOne(4); // 5
denque.removeOne(3); // 4
denque1.removeOne(1); // 2
```
<hr>
#### `splice(int index, int count, item1, item2, ...)` -> `array`
Native splice implementation.
Remove number of items from the specified index from the list and/or add new elements.
Returns array of removed items or empty array if count == 0.
Returns undefined if the list is empty.
```js
var denque = new Denque([1,2,3,4,5,6,7]);
denque.splice(denque.length, 0, 8, 9, 10); // []
denque.toArray() // [ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 ]
denque.splice(3, 3, 44, 55, 66); // [4,5,6]
denque.splice(5,4, 666,667,668,669); // [ 66, 7, 8, 9 ]
denque.toArray() // [ 1, 2, 3, 44, 55, 666, 667, 668, 669, 10 ]
```
<hr>
#### `isEmpty()` -> `boolean`
Return `true` if this queue is empty, `false` otherwise.
```js
var denque = new Denque();
denque.isEmpty(); // true
denque.push(1);
denque.isEmpty(); // false
```
<hr>
#### `clear()` -> `void`
Remove all items from this queue. Does not change the queue's capacity.
```js
var denque = new Denque([1,2,3]);
denque.toString(); // "1,2,3"
denque.clear();
denque.toString(); // ""
```
<hr>
