This part of the book introduces the main concepts of Ajax. Chapter 1 presents Ajax and reasons to use it. Chapter 2 covers the technical fundamentals,
and shows how they fit together. The aim is that, by the end of the book, you’ll be able to tackle real-world projects bigger than a “hello world.” Chapter 3 introduces the software development tools that we’ve used to manage large projects, and shows you how to use them with Ajax.
