In case you have missed it, I can recommend a tool called JSLint. It goes through your JavaScript for common pitfalls, performance issues and makes sure it's standards compatible.
The first step is to download the jslint.js file. Since it's a JavaScript program, you need a JavaScript interpreter to run it, e.g. Rhino or node.js. This is how you install and run it on an Ubuntu system:
$ apt-get install rhino
$ rhino /path/to/jslint.js /path/to/your/script.js
The output might hurt your feelings, but is a real time saver when hunting down cross-browser issues etc. If you need to tell JSLint about global variables, e.g. the jQuery $ sign, you do so with a special comment at the top of your JavaScript source file:
/*global alert: true, window: true, $: true */
Read more about other options here: www.jslint.com/lint.html
Also, you can use JSLint in the browser just by pasting your code in the text box over at www.jslint.com
