Things To Look in JavaScript Libraries

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:

1. It should simplify HTML traversing and DOM manipulation
2. It should simplify handling of events preferably unobstructively
3. It should simplify Ajax implementation
4. It should simplify animation and visual effects
5. It should have a small footprint i.e. its size should small
6. It should be easy to integrate (or easy to make it communicate) with server-side logic.
7. 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!
