I don't see how this example justifies your position, though. Nobody will ever write "++[[]][+[]]+[+[]]" to mean "10" in anything but an obfuscated code contest.
No they will, in every horribly thought out interview that someone who thinks they are smart writes in on a white board and asks applicants to solve it. As if these trick questions some how give insight into ones ability to solve real world problems. These are exactly the kind of obscure fringes of a languadge that an interviewer with an ego loves. When they reality is whether one can solve it or not, amounts to a hill of beans as to whether one is a good JavaScript programer or not. In fact if they are using these fringe practices in their code base they are writing unmaintainable code, which makes them a less desirable developer.
I agree that 'magic code' and obfuscation is pretty much ego stroking, but this doesn't seem like a good argument against the whole idea of using weakly typed languages.
No I was not arguing against weak typing, just taking the opportunity to highlight how these kind of questions are used. I have no issue with weak typing. I don't get too dogmatic about such viewpoints. My comment was rather an attempt to highlight where a lot of this type of trivia knowledge is used and misapplied.

Great, then you know who not to work for.
