Nowadays, JS libraries are everywhere. The choices are so many that lot of us are left confused, not knowing which one to have, and which ones to ignore. After going through the same confusion, I came up with the following features that I look in a Javascript Library:
- It should simplify HTML traversing and DOM manipulation
- It should simplify handling of events preferably unobstructively
- It should simplify Ajax implementation
- It should simplify animation and visual effects
- It should have a small footprint i.e. its size should small
- It should be easy to integrate (or easy to make it communicate) with server-side logic.
- It should be easy to learn.
Any JavaScript library having the above features should be a good one. But having said that, I already can name a few with all the above features. But hey, nobody said it was going to be easy! 
Good info. I have a question. I cannot insert javascript on wordpress blog. Do you have any tips?
@Gontua
Well, not really :s
As far as I can tell, WordPress.com doesn’t allow insertion of Javascript. The only solution that I can suggest you is to move to your own space where you will have the complete freedom(depending on your server options though) of doing whatever u feel.
I hope I was helpful.

@Javito:
Well I havent really got into YUI that much, just peaked at it from outside
But, from what I have been able to understand, it seems to be a very good library. They have very good documentation to start with.
It seems to be more than a simple JS library in that i has more features than a basic library should have. And, that I dont like so much. I want my library to be small, doing particular and basic jobs for me. Also it seems to be very much namespaced, so to access any functionality I had to type quite alot (im sure they have shorter alternatives that I still didnt come across).
Its too bulky for me, but its definitely not bad once you get used to it.
My friend told me that it found out the way to increase the font size for the img replacement. He also said the it made up by himself, but I am far to believe that
. The new way I know is using Sifr technique but is not increasable.
Do you know anything about?
