Debugging

When writing code, you will inevitably introduce bugs. A bug is something that messes up the program and makes it do something you didn't want it to do.

Debugging is the process of finding and fixing problems in your program. To be more specific, it is the process of figuring out what code actually does, comparing it with what you intended, and making changes to the program to make it do what you intended.

The word "actually" is important here: The computer just does what your code tells it to do. It doesn't try to interpret what you want it to do.

One of the first rules of debugging is to assume that the mistake is in your own code because most bugs are in the code that we wrote. Don't dismiss bugs as someone else's problem (even when it's not your fault). Part of our role as developers is to provide users and players with the best experience that we can.
