AJAX Patterns and Frameworks

I’ve been doing AJAX programming for several years (ever since I learned about XMLHttpRequest) but of course it didn’t have a cool name before. Many of the patterns I’ve used have not been cataloged before but I was delighted to run across this site that speaks specifically to AJAX Patterns. My favorite page is on AJAX Frameworks because even though I’ve built thousands of lines of JavaScript code to support my AJAX needs many of the frameworks on that page seem more reusable so I’ll be switching out some of my old code and replace it with one or more of the newer ones.
