webreference.com just posted this very nice roundup of JavaScript libraries and framework here.
It covers:
- Prototype (there’s another article on Prototype from the same author here)
- script.aculo.us
- MooTools
I will also cast my own vote for some that aren’t on the list (though the article says his article next week will cover some of these):
Which ones do you rely on?
Which ones are a love/hate relationship?
Which ones would you sooner give up chocolate than stop using?
