The Most Common Coding Mistakes (and How to Avoid Them)

The Most Common Coding Mistakes (and How to Avoid them) The most common mistake beginner programmers make is bad variable naming. Backing up your code is extremely important, even if you are not working on a team. Don’t make functions that take in many inputs, or functions that only accomplish one very specific task. Break up your function into multiple other functions, which are easier to read and maintain. Use the debugger when you run into a code error that you do not know how to solve.
