I will recommend the book i'm currently reading: Secrets of the Javascript Ninja: http://jsninja.com/ http://jsninja.com/. It is written by Jquery author, and it shows you basically how a framework like JQuery would be written. It is not a book for the faint of hearts, very in depth treatment of various aspects of javascript, such as functions/closures/timers/cross platform javascript development etc. You probably need Wrox Professional Javascript for Web Developer (2009) to brush up on the basics first. Happy coding!
