Sams Teach Yourself JavaScript and Ajax

This DVD is a good way to learn the basics of JavaScript and Ajax (and there's even an intro to CSS).The problem is that I see errors popping up all over the place.

Teach Yourself JavaScript and Ajax Video Learner Kit offers a self-paced guide to video lessons explained by key concepts, and tells what to do through hands-on learning labs. Four hours of video lessons on a DVD accompanies instructions on how to build dynamic web pages and how to control CSS with easy JavaScript.
