Some times it&squo;s hard to find information that is really important to development. I thought that I would include a link to a very important web page in regards to understanding the proper implementation of closures in javascript.
If you read http://jibbering.com/faq/notes/closures/ you will find some interesting information in regards to how a lot of popular frameworks are built. In Particular the section on Associating Object Instances with Instance Methods contains important information on hooking up event handlers with parameters. There are also some important sections on Garbage Collection.
