## Install

```

## Install

Install with [bower](https://bower.io/)

```sh
$ bower install arr-flatten --save

## Usage

```js
var flatten = require('arr-flatten');

flatten(['a', ['b', ['c']], 'd', ['e']]);
//=> ['a', 'b', 'c', 'd', 'e']
```

## Why another flatten utility?

I wanted the fastest implementation I could find, with implementation choices that should work for 95% of use cases, but no cruft to cover the other 5%.
