Description
Functions are one of the core building blocks of programming, and they're much simpler than they may initially look.
In this lesson, you'll learn how to create and call Swift functions, why functions help you avoid repeated code, how scope works, and how parameters allow you to pass data into a function.
We're learning only what we need right now because in the next lesson we'll use these functions directly inside our Quiz App.
