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 the amazing guy [@barberboy](https://github.com/barberboy).
[`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]
```
