Changes

This book assumes that the reader has some experience in designing web pages using either HTML or XHTML. Experience using other programming languages is a benefit, but not a requirement when reading this book. Every effort has been made to carefully explain the concepts of JavaScript to make this book accessible to those with little or no programming experience. The early chapters of JavaScript Essentials cover the basics of the JavaScript scripting language with plenty of examples illustrating the topics covered and providing "cut and paste" solutions to common problems. It is hoped that after completing this book, the typical reader will be confidently adding dynamic, JavaScript powered content to their web sites.
