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.

You're in Section 01 of Composing Closures and Callbacks in JavaScript.

    The breakdown of what the nest function does would help for a better understanding of lesson number 7

    What did you like about this course?

    This got really dense really fast; that it's promised we'll slow down and work through this is encouraging.

    What was your strongest take away from this collection?

    This is just my opinion. This is introduction to Callbacks and other stuff. I don't think assuming that viewer knows what's pipe and compose is a good way. It would be nice to include some more information about those if you're using them in video. Beside that it is fine :)
