## 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 ]
```

### Load anywhere
This library is compatible with Node.js, the Web and any style of module loader. It can be loaded anywhere, natively without transpilation.
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.mjs'
```
Old browser (adds `window.arrayBack`):
```html
```
