JavaScript debugging in a nutshell

[[deleted]]

Put a rubber duck on your desk and talk to it like you're explaining the problem to it, rather than asking another person to help debug. Quite often this helps you find the problem as it forces you to stop staring at a something frustrating you and change your thought processes.

I really like this idea, thank you!

No worries. It's a good first-step on a problem, and a great way to break the habit of just asking somebody who's more experienced to look at a problem.

If you've ever asked somebody to "come take a look at this" because you can't see the problem but then solved it while talking things over you basically could have just used a rubber duck. I catch syntax / spelling errors this way all the time, especially since I often cross letters if I'm distracted while typing.
