> I've never had a case where I didn't know the reason or mechanism by which an element would be hidden. Unfortunately, I usually don't keep the whole codebase in my head (including libraries), so I often don't know the reason. The more general point is that I don't want to have to know, because the mechanism of how it is hidden is not what I care about. > It's not quite as succint as your jquery, but you also could have written this.
