An Introduction to the Book Samples

As I mentioned earlier, the goal of this book is to teach you how to create reusable Ajax applications with object-oriented JavaScript. Instead of creating individual samples with no context, I have decided to create individual samples that are usable on their own and as a part of larger web applications as a whole. Therefore, we will learn how to create an Ajax engine, components, and connections to databases as individual chapter samples, but we will also combine these individual pieces into a larger application that will be continually built throughout the book. The final application will consist of all the individual pieces tied together by Ajax to create an internal web mail application that can be used in any user-based application, such as a community-based web application, for example.

The samples that are used in each chapter and ultimately for the final application can be found at samspublishing.com. Within each chapter, the samples that correlate to the final application will be denoted with listing headings that identify each code snippet. Not only will you learn how to create and use your own reusable Ajax components, but you also will learn how to utilize their reusability by connecting them to any future Ajax applications that you build.
