Efficient JavaScript talk

Watch it @ the YUI Theater or download for Quicktime

5 lessons to retain from the talk:

1. Don't modify visible objects: hide, modify, display.
2. Best way to append multiple elements: remove node from DOM, append elements, re-attach element to DOM.
3. Beware of the markup maintenance issues caused by the use of innerHTML.
4. Avoid internal browser reflow (repositioning) by caching element properties.
5. Rather than binding events to every element inside a container, bind only to the parent container. It is easy to access each of its children by id.
