What is an "app"?

Apps are a way for programmers to compartmentalize their code.

Think of functions in python. Do we technically need functions? No! We could literally write all of our code in one long, high-level script. Would the code run? Yeah! Would it work? Yeah! Would you get laughed at if anyone ever saw it? Yeah!

This isn't the most comprehensive explanation of apps, but it's good enough for now. You'll see examples throughout the rest of this tutorial which will iron out the use case for apps.

Main Point: Apps are a way for programmers to compartmentalize their code.
