<a name="module_array-back"></a>

## array-back
Takes any input and guarantees an array back.

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

**Example**  
```js
> const arrayify = require('array-back')

> arrayify(undefined)
[]

> arrayify(null)
[ null ]

> arrayify(0)
[ 0 ]

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

> arrayify(new Set([ 1, 2 ]))
[ 1, 2 ]

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

Node.js:

```js
const arrayify = require('array-back')
```

Within Node.js with ECMAScript Module support enabled:

```js
import arrayify from 'array-back'
```

Within an modern browser ECMAScript Module:

```js
import arrayify from './node_modules/array-back/index.js'
```
