I regularly use FireBug in Firefox my for my JavaScript debugging. Back in the mozilla days I would just enter javascript: in the address bar and get the nice dialogue that shows to tell me the location of the error. We can all agree we have come a long way. Now that Firebug is also in Chrome we have another tool. I admit I do not bother with JS debugging in IE much, but I have pressed F12 a few times in the app to get up the dev tools.

So to put it short I could not do as good of a job as the guys over at alistapart.com. Check out what they have to say about debugging in JS “after the jump”:

“When used effectively, JavaScript debuggers help find and squash errors in your JavaScript code. To become an advanced JavaScript debugger, you’ll need to know about the debuggers available to you, the typical JavaScript debugging workflow, and code requirements for effective debugging. In this article, we’ll discuss advanced debugging techniques for diagnosing and treating bugs using a sample web application.”
