egghead.io developer chats Learn To Debug Properly And Ask Better Questions With Justin Samuels
How many of us still almost exclusively use console.log() when trying to debug something? It's okay, plenty of us do it that way, but you could be saving yourself a lot of pain and suffering by using the debugger and stepping through the execution.
There are several advantages to using a debugger, you get a tighter feedback loop, a lot more information, and it allows you to go into places you wouldn't have even thought about.
Now debugging can take you far, but there are times when we need another human to help us. Asking questions is anxiety-inducing, "what if this is something I should already know?" "am I being annoying?" "am I interrupting them from doing something important?"
The key is to remember that there is no such thing as a dumb question, but there are questions that haven't been thoroughly vetted. Stack overflow has an excellent wiki on asking good questions. Learn how to form good questions, and everything will end up being okay!
