JavaScript Debugger [closed]

Answer 1

The Google chrome browser has a reasonable wee JS debugger built-in. There's a good list of the available commands here.

Answer 2

IE8 beta 2 has a nice debugger

Answer 3

If you're accustomed to using Firebug, you might like Firebug Lite, implemented in JavaScript. You can use it as a bookmarklet, which is nice. I'm not sure how powerful it is, I imagine other, "real" solutions are better, but it's handy in a pinch.

Answer 4

Aptana Studio IDE has a nice javascript debugger.

The community version supports only Firefox, the professional one also supports Internet Explorer.

Answer 5

Take a look at Venkman, the JavaScript debugger for Firefox:
