Introduction

This is another week of JavaScript. This time I'll talk about the DOM and JavaScript libraries. I'm going to focus on jQuery and demonstrate some of the basic things you can do with it. I will also show how you can accomplish some of the same tasks without any JavaScript libraries and you can decide if it's easier to use a library or to write the code by hand.
