Ask HN: Simple, fast JavaScript Framework?

Hi, Can you suggest a basic JavaScript framework, please? Basically, it should be: 1. Compatible with most browsers. 2. Only DOM manipulation(select elements by ID and class, listen to events, etc.) No animation stuff is needed. 3. Very fast, very small. -- Basically, I could stick with JQuery, Dojo since I know these two. But is there any good alternative which does only the most basic stuff? Thank you in advance.
