Array.unappend

Splits a non-empty array into all elements except the last, and the last element.

When to use

Use when you need to split a non-empty array into the elements before the last element and the last element.

Details

Returns a tuple [init, last] and requires a NonEmptyReadonlyArray.

Example (Destructuring init and last)
