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

> arrayBack(undefined)
[]

> arrayBack(null)
[ null ]

> arrayBack(0)
[ 0 ]

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

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

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