Real World XML

Chapter 6. Understanding JavaScript

This book is written to require only knowledge of HTML before starting because we're covering XML from scratch—and that means many readers don't come to this book with a programming background. However, XML is a natural for programming because you can tell a browser how to handle your documents if you do use programming. Fortunately, we won't have to learn a lot about programming here; all we'll need to understand are the fundamentals of JavaScript to work with XML in a browser. If you already know JavaScript, feel free to skip this chapter; if not, this chapter is here so you don't have to run out and buy a book on JavaScript before proceeding with the work we'll be doing in the next few chapters.
