with JavaScript libraries. Don't pull in a 100K library to get a couple of useful functions. Write them yourselves. Avoid getting caught in a maintenance trap.

While I agree with a lot of the rest, I'm not sure I understand this part... a 19k library (jQuery) that gives you a single DOM interface that fully takes advantage of JavaScript and works in every major browser is what will keep you out of the maintenance trap, not writing/maintaining that interop code yourself.
