Before we dive deep into the pattern of composing callbacks and closures, we need to take start with the definitions and basic building blocks that we will be using for the rest of the course.

You'll be able to answer questions like:

What is a Closure?
What is a Callback?
Why does Callback Hell happen and how can we handle it?
We will see that by establishing a contract between functions and holding to the pattern that is established, you will have gained a lot of power and flexibility in writing reusable, robust functions.
