JavaScript Source Code Analyzer

JSLint has historically been the main tool for this, but several more now exist:

• JSHint - a fork of JSLint that is said to be a little less opinionated
• Closure Linter - a linter that checks against the Google Javascript Style Guide
• ESLint - a more flexible tool, but newer, and not yet as stable.

JSAnalyse has just been published on codeplex. It is a tool which analyses the dependencies between javascript files. You can even define the allowed dependencies and JSAnalysis checks whether the defined rules are fulfilled or not. That allows to keep track about the javascript dependencies even in big projects and to have a clean architecture.

JSAnalyse can be executed as a command line tool or configured via the Visual Studio Layer Diagramm. It is also easy to integrate into the build. With gated check-ins you can keep the dependencies under control.

I have found JSLint which helps correct a lot of common errors and such; however, I'm hoping to find something that I can add my own rules and such to help automate some coding standards stuff that my company is wanting to implement into JavaScript.

I need to look into it's extensibility model more.

There's a few tools on the list of tools for static code analysis at wikipedia that has JavaScript support, you can allso see JavaScript Debugging if any of the tools mentioned would help. There's allso a few good tools at YUI (Yahoo! Developer Network), as well as a lot of helpful components.

I've allways used JSLint myself, and that's the only analysis tool for JS I've tried. I've grown more and more fond of JavaScript, but good tools is still a problem. :(

I use Aptana for JavaScript file analysis. It catches alot of goofs (if condition with a single =). It also describes the class layout. I believe it has a jslint implementation embedded in it.
