Go beyond console.log with the Firefox Debugger

Promo art for the Firefox Debugger Playground: a styled insect with the words "go beyond console.log" below it.

console.log is no debugger. It’s great for figuring out what your JavaScript app is up to, but it’s limited to spitting out a minimal amount of information. If your code is complex, you’ll need a proper debugger. That’s why we’ve added a new section to the Firefox Devtools Playground that’s all about debugging. We’ve built four basic lessons that use the Firefox Debugger to examine and repair a simple JavaScript to-do app.
