It's possible that you are using the wrong data type for the job (an
array is very different from a list, so if you need a list an array
might be a bad fit).

Anyway, if you are using the new ECMAScript you might find that

  !array.some(() => true)

does what you want or even (depending on how you handle deleted
elements) the much cheaper array.length == 0.  For example, if you use
push/pop/ shift/unshift to add and remove elements you'll find an
empty "list" has length zero.
