I can't really understand what this is trying to say. It must be because I don't understand "iterable". Doesn't it just mean "responds to for-of"? I would imagine arrays, NodeLists, arguments, and other array-likes all respond to for-of; if they don't, that seriously decreases the utility of for-of!
