## array-back
**Example**  
```js
const arrayify = require('array-back')
```
<a name="exp_module_array-back--arrayify"></a>

### arrayify(input) ⇒ <code>Array</code> ⏏
Takes any input and guarantees an array back.

- converts array-like objects (e.g. `arguments`) to a real array
- converts `undefined` to an empty array
- converts any another other, singular value (including `null`) into an array containing that value
- ignores input which is already an array

**Kind**: Exported function  

| Param | Type | Description |
| --- | --- | --- |
| input | <code>\*</code> | the input value to convert to an array |

**Example**  
```js
> a.arrayify(undefined)
[]

> a.arrayify(null)
[ null ]

> a.arrayify(0)
[ 0 ]

> a.arrayify([ 1, 2 ])
[ 1, 2 ]

> function f(){ return a.arrayify(arguments); }
> f(1,2,3)
[ 1, 2, 3 ]
```
