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] | ||||
``` | ||||
