Debugging / analyzer tool for Javascript?

Question

Please suggest if we can use any static analysis tools for Javascript? Can parasoft tool be used? Any tutorial on parasoft would be helpful.

Are there any other debugger alternative to Opera dragonfly?

Thanks

Answer 1

Static analysis:

• JSLint
• JSHint
• Google Closure

Debuggers:

• Chrome Inspector ( F12 in Chrome )
• (FireFox) Firebug
• (Many Browsers) Firebug Lite
• (Mobile Webkit) weinre

The IEs have a few debuggers, some come with MS Office, some with Visual Studio, its sort of a mess, and I don't have great resources for that.

Static analyzers for JavaScript are fairly limited because of the linkage patterns and dynamically defined objects.

Answer 2

If you need to debug javascript for front-end web development, then the debugger that I find most useful is the IE9 debugger. I am aware that there is a lot of bias against internet explorer, but the debugger is really good and when an exception is thrown you would actually get a window for it.
