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

> 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 ]
