What's your favorite Javascript library?
jdp: I use jQuery. I only briefly checked out prototype before I found jQuery, and I don't remember anything about it. Like most of us, I got tired of using the same thing over and over so I checked out MooTools and didn't like that it had all sorts of $chk- and $empty-like identifiers, but otherwise it's a solid library. I ended up sticking with jQuery because it's what I like and what I know the best.
