I don't think this kind of questioning is useful. Does it really matter if the dev knows all the strange intricacies of javascript, or does it matter if they can actually put together a well engineered application? I can easily see a more big-picture oriented dev who only uses the bare minimum javascript features fail this test yet create very well engineered code. I can also easily see a dev who likes to study manuals doing well on this test and then making code so difficult to understand he can't even fix it himself.
