What is Functions?

Functions let us group a series of statements together to perform some task. Once a function is created, it can be reused over and over in your code. If you find yourself repeating statements in your code, then a function may be the answer to avoid that repetition.

Pro Tip, Good functions accept input and return output. Bad functions set global variables and rely on other functions to work.
