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. -- Ben.
