Firebug includes a powerful JavaScript debugger that lets you pause execution at any time and see what each variable looked like at that moment. If your code is a little sluggish, use the JavaScript profiler to measure performance and find bottlenecks fast.

If you are using FireFox then Firebug is perfect for this application. I'd highly recommend it for debugging javascript in browser.

Looks like this would be a good answer for you too.

It depends on your browser... If you're using Chrome (that's what i'm using...):

  • Open up the page
  • Right click anywhere -> Inspect element (opens up Dev toolbar)
  • Go to Profiles tab
  • Click the little "recording" icon (cirle) at the bottom of the screen (4th button)
  • When it's read it's indicating it's recording
  • Do your thing
  • Click the rec button again
  • enjoy the statistics
