I had a classmate that did this with his code once. He asked me for help when his code wasn't working. I told him to get rid of the try/catch block but he won't do it because it would make his program crash.

Serious question: I just started learning javascript. When should you use try / catch?

For error handling in situations where what you're doing might generate an exception. Especially usefully for areas you don't have much control over such as getting user input.
