The JavaScript Pocket Guide - JavaScript over the years has really prgressed into the most used programming language on the web today. Almost every website today uses some form of JavaScript, whether it be used within a server-side programming technology like ASP.NET or a JavaScript library like jQuery or Mootools, or YUI or creating UI components like widgets. JavaScript is everywhere and if you do any sort of web design or development you need to get a hang on it. There are lots of online resources on JavaScript, and I mean LOTS. But it may take you awhile to go through it all to find what you specifically want. So there are LOTS of books you can get as well on JavaScript, but if you already have a basic understanding of JavaScript, most are way more than you need.
