What every intermediate and advanced developer needs to know!

Do you want to dive into three of the trickiest aspects of the JavaScript language? From beginner to intermediate - this course will bring you up to speed on some of the must have knowledge of being able to write in it effectively, while demystifying some its most often-misunderstood constructs!

In this course, you will learn all about scopes, “this”, and prototypes! Training content often doesn’t dive into the specifics of the nature of these “advanced” features. However, it is my belief that this is necessary knowledge to be an effective JavaScript programmer!

My goal at the end of this course is that variable scoping, the usage of the “this” keyword, and the creation and use of prototypes is well understood from a ground up perspective without compromise. Simply by having a firm grasp on these aspects of the language, many issues that even years-long JavaScript developers face can be resolved easily!

We will discuss, in depth:

  • Scopes and Closures

  • Immediately-Invoked Function Expressions (IIFEs)

  • Hoisting

  • The “this” keyword

  • The call/apply/bind functions

  • The nature of the magical “new” keyword

  • Object and function prototypes

  • And more!
