> Faster, node.js focused alternative to JavaScript's native array map.
## Install
Install with [npm](https://www.npmjs.com/):
```sh
$ npm install --save arr-map
```
## Why use this?
JavaScript's native `Array.map()` is slow, and other popular array map libraries are focused on browser compatibility, which makes them bloated or less than idea for non-browser usage. This implementation is focused on node.js usage keeping it light and fast.
## Usage
```js
var map = require('arr-map');
map(['a', 'b', 'c'], function(ele) {
return ele + ele;
});
//=> ['aa', 'bb', 'cc']
map(['a', 'b', 'c'], function(ele, i) {
return i + ele;
});
//=> ['0a', '1b', '2c']
```
