Great article and discussion. For my 2cents when I cache jquery objects I usually suffix with $ so I can remember that this is a jquery object (so “block$” instead of “block”). This is especially useful because I frequently grab the DOM node directly to work with it, so this avoids confusion about which thing I’m actually working on. I realize some people may dislike this for all the usual reason any Hungarian-ish notation is disliked, but in this case I find it very helpful.
