Advanced Web Technology presentation

from the slides, i liked; why use js libs, libs showcase, and creating DOM smartly (good sequence). i didn't realize that jQuery was slow, i've been having performance issues, but i also think it's from some of my rushed code.

I wouldn't say jQuery is slow per se, it's just that the idea behind jQuery is smartness and not performance - - and this smartness could become costly in very complex JS applications (e.g. Zimbra, Gmail, Yahoo Pipes etc.)

But really, jQuery is a great library and I think most web-applications today could use it without any performance issues.

After profiling (w/firebug) my script, the jQuery function 'filter' consumes the largest percentage. I'm curious if this is part of the smartness, and part of what is costly. Time for a rewrite. :)

Good presentation. But I think that Prototype is more Ruby than Java orinetated (YUI smell more like Java).
