This chapter served as something of a wrap-up for the entire booka weird wrap-up because, although Ajax has been around for several years, it is still evolving. Examples of this are Sarissa, JSON, and Microsoft's ATLAS, different approaches to solving what is basically the same problem. I also made mention of both the World Wide Web Consortium and SourceForge, with the former being useful for documentation and the latter being useful for development tools. For those of us whose spouses insist upon wasting money on the mortgage instead of development tools, those SourceForge tools come in handy. Finally, I gave the web addresses for the web browsers available at the time of this writing.
