array-from

==========

**A ponyfill for the ES 2015 [`Array.from()`][].**

*** Ponyfill**: A polyfill that doesn't overwrite the native method.  

*** ES 2015**: The new name for ES6 that [nobody expected][].

Modeled after the final ES 2015 spec. Credits for the implementation go to the amazing folks of the MDN and [our awesome contributors](https://github.com/studio-b12/array-from/graphs/contributors).

 

[`Array.from()`]:         https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/from                  "Array.from()"

[nobody expected]:        http://webreflection.blogspot.de/2015/01/javascript-and-living-ecmascript.html                               "JavaScript and the living ECMAScript Standard"

Installation

------------

```sh

$ npm install array-from

```

Usage

-----

Recommended:

```js

var arrayFrom = require('array-from');

  // You’ll get the native `Array.from` if it’s available.

function () {console.log(

  arrayFrom(arguments).map(require('1-liners/increment'))

);}(1, 2, 3);

//» [2, 3, 4]

```

You can also use it as a classical polyfill. It’s [not recommended][], but sometimes practical:

```js

if (!Array.from) Array.from = require('array-from');

  // This will affect all loaded modules.

function () {console.log(

  Array.from(arguments).map(require('1-liners/increment'))

);}(1, 2, 3);

//» [2, 3, 4]

```
