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.

• Create a Function to Configure setTimeout
• Return a Function to Cancel an Async Behavior
• Wrap addEventListener in a Function for More Control
• Create a Utility Function to Control setInterval
• Combine Multiple Async Behaviors with a Merge Function
• Use Lodash Curry When Functions Return Functions
• Match Function Requirements with Lodash Partial and Flip
• Create a Buffer to Pair Values Together with Zip
• Pass an Array to a Callback with a forOf Function
• Pass a Done Symbol when an Async Function is Done
