How to debug javascript program.

Question

Hi All.

I can't find great way to debug javascript. I know firebug on firefox, but it's not best way I think. I want to put break point and trace program but I can't with it. Do you know good tool or how to trace the program.

Answer 1

I find IE 8 Developer Tools (built into IE 8) and Visual Studio (2008, Express is free) are an excellent way to debug JavaScript -- at least in an environment compatible with the above tools :-)

Answer 2

Venkman JavaScript Debugger

Answer 3

Firebug Extension for Firefox (Yes, it also supports brakepoints) or the Webkit Inspector that's built into Safari and Chrome by default.

Both offer JavaScript debugging/profiling and a lot of other useful features.
