Foundations of Ajax is written to give you, the developer, all the tools you need to add Ajax techniques to your existing or future applications.Our motto while writing this book was, “Everything you need to know; nothing you don’t.” We assume that as a reader of this book you a real ready an experienced Web application developer. Because of this, we focus on the
topics that are most likely new to you: Ajax and its associated tools and techniques. Wedon’t spend much time talking about server-side languages because we assume you will develop server-side functionality using the tool set of your choice and that you don’t need our help doing it. We don’t spend time talking about how to build enterprise-scale applications that just
happen to use Ajax. Instead, we focus solely on Ajax and its related tools and techniques.
