Establish Callback and Closure patterns Around Async Browser Behaviors
JavaScript is full of inconsistent APIs. Wrapping those APIs in functions allows you to have full control over how to configure them and make them more reusable.
This becomes even more beneficial when dealing with the async nature of JavaScript. You'll learn how a broadcaster is a function that wraps another function (which we call listeners) and modifies the behavior. We will build up this pattern in a way that allows you to compose broadcasters together making your code more reusable.
You're in Section 02 of Composing Closures and Callbacks in JavaScript

The concepts were nicely broken down and we gradually move to more advanced scenarios throughout the course. Also, I really liked the examples like grouping behaviors using the zip function.
