Prototype with Scriptalicious all the way! For the very reason that Prototype (and of course JQuery), are both up there in #1 and #2 spots! I won't say which is in which position as I don't want to stir anything up :)

I am using Jquery for my research. :)

What research would that be?

Damn, I just hate jQuery now, it is so frustrating to work with and documentation is crap!! No longer using it!!

Really? I'd have thought JQuery, being one of the daddies when it comes to Javascript libraries, would have an awesome documentation. To be honest though, you can't beat the extent in which Prototype document their Javascript library. It's truly awesome!

Hard to hear you saying that Sam, for me jQuery is the one i feel more comfortable to work with as it cant get much more intuitive and easy than that. Im definitely not using JQueryUI although it looks like it could have a bright future. As for the documentation, i think the one in their website is ok, but you might also wanna try looking in their google´s group where theres a lot going on.

It does look like a well documented Javascript library if I were honest - from my initial observations. Perhaps Sam found a third-party documentation and thus came to the premature conclusion that it was terrible? I don't know.

How would you rate JQuery's documentation in comparison to Prototype, Sam?

Used sajax until I found xajax.
Using JQuery for js, so much lighter and easier to use over the other js libraries.
Right now I'm playing with YUI, nice for the extras.
It really depends on the project at hand.

I rarely use any javascript, but lately I did few things with prototype, and it's really great! Really easy to use.

AJAX really is pretty simple stuff, I'd also recommend making it many times easier by utilising JSON as well. Although when you use JSON you'll have to be careful not to eval() anything, but rather use the Prototype's in-built function, evalJSON(). Also don't forget to set the content-type of the JSON document to application/json.

My favorite AJAX framework is jQuery because of its simpleness and its speed. I've read in their blog that the version 1.1.3 had a speed increasement of about 800%!
Actually, I'm not doing much web stuff anymore since I've discovered PHP-Gtk.
