I would assume [1] + [2] would give you either 0 or 2, but maybe "12". But why you ever write that? I’ve never bothered to memorize what happens there because I would never write that. The plus operator is not for arrays. It’s for numbers and strings. If you’re trying to concatenate arrays, there’s a function for that. Would you do that in Java or C? People trying to make JavaScript do silly things just because it refuses to crash when you do then calling the language bad for it is just silly to me.
