What are JavaScript functions? They're the "subprograms" that power your code. You truly master the use of JavaScript once you learn how to work with functions. In this course, author Ray Villalobos explains how functions work, how they're declared, and how they're invoked, and then issues a challenge exercise that allows you to test your knowledge. In the third and final chapter, he'll show you how to set up anonymous closures and create JavaScript modules that make your code easier to reuse.

Topics include:
  • What are functions?
  • Using functions as objects
  • Understanding call-and-apply invocation
  • Using the arguments parameter
  • Returning values
  • Understanding hosting and variable scope
  • Chaining module method calls

Welcome

Hey there this is Ray Villalobos, and welcome to JavaScript Functions. In this course I'm going to take a deep dive into the functional nature, and some of the patterns that are commonly used when working with functions. I'll start by showing you how functions work, how they're declared, and invoked. Then we'll examine how all functions are JavaScript objects, and the implications that has on your app development. We'll do an exercise that tests your knowledge of basic JavaScript function concepts.

Finally, I'll show you how to setup anonymous closures. And walk you through creating a JavaScript module, so you can use to make your code easier to reuse across projects. That's enough talk, let's get started with JavaScript functions.
