I played around with jQuery a little over the weekend. I’m fairly impressed. The obvious comparison is with Prototype, but I can’t really make that comparison because almost all the Prototype work I’ve done has been automatically generated by Rails. Certainly the code I hand-wrote over the weekend seems more concise and expressive than the generated Prototype code I’ve seen; but part of that may just be an artifact of being handcrafted.
I was going to post some code, but the WordPress editing interface seems to be extremely unfriendly to pasting code snippets.
