Yep.

Because an array is an object which has a 'truthy' value '![]' evaluates as 'false'.

Simplifies to a statement similar to 'false == false'.

A little useless arcana for those interested.

Well, not so useless if your expecting '!someEmptyArray' to evaluate to 'true'. Use '!someEmptyArray.length' instead.
