Description

Using array_first or array_last on an empty array will return undefined, rather than resulting in a crash.

This behavior is fine, but maybe should be documented so it is clear if this is intended or not?
Something like:

"RETURNS:
Any (Any valid data type that an array can hold) or undefined if the array is empty"
