Making Things Modular

To make our code easier to understand what we have, to manage what we have, and to find what we want, we have to separating and grouping sentences. If we have a lot of code and we just write it as one continue list of statement, reading it can be really difficult. So we're not doing that.

First, we can separate our code to multiple file, but don't stop there. Within those files, the code can be grouped and divided into multiple meaningful section.

So in this section we will learn all about separating and grouping sentences the right way.
