 Before we can learn about the details of writing a function, we need some insight into their purpose in software. Functions are small tasks that help accomplish larger tasks, which in turn help solve larger tasks, and so forth. We think you already have a lot of intuition about breaking apart large tasks into smaller tasks that you’ll be able to bring to bear in this example:
