Debugging Javascript

Debugging Javascript can be a pain. Most of the time you use alert() calls or some other mechanism to trace information, but this is clunky at best. Even if you have a full fledged debugger at your disposal, debugging javascript can be a pain.

But when I found out about the “debugger;” statement. This is essentially a hook into the debugger you have installed: when the engine encounters this, I’ll fire up a debugger and set the current execution point to the debugger call. You can step through your code from there.

Nice.
