Java Worker Javascript Debugging Tips?

Does anyone have any tips for debugging java workers? Is there a way to step through the code? I poked around a bit in the Chrome developer tools Sources and other selections, but couldn't find much. If there isn't a way to step through it, does everyone (generally speaking) just put in console.log() commands to get info during runtime? Thanks!

Here's a couple threads I used to help me to workout js issues.  ;-) [SheetWorkers] Debugging advice: How to debug these things? [SheetWorkers] Debugging Advice - Part Two.

If you're savvy to debuggers and you're in Chrome, putting the keyword "debugger" in your code is the easiest way: on('change:foo',function(){ debugger; // some code }); If you have the debugger open it will stop on that statement as if you'd set a breakpoint there. You can then go off and set other break points.  Also, checkout the  debugging functions in TheAaronSheet . They give you colored log messages to make tracking things down easier.
