<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 ]

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
<script nomodule src="./node_modules/array-back/dist/index.js"></script>
