Web Dev .NET: Control the Complexity of Your JavaScript Functions with JSHint.
I’m quite hooked on JSHint if I’m honest. I’ve used to run to linters before our in-browser tools become so advanced and useful. Since then my toolset has embraced linting on many levels and apps like CodeKit will auto-hint your JavaScript on save. You can learn a ton about writing good JavaScript from tools like these, and I recommend having a look if you’re currently not taking part.
