11 JavaScript Features Critical to Understand

If you work with JavaScript at all, you need to understand and be able to work with its most critical features.

In this course we focus on 11 of those critical features. Each feature is addressed on its own, but the course is also structured to build on the previously taught features and concepts. We start with some of the most basic features like scope and hoisting, but eventually tackle more complex features like closure and immediately invoked function expressions.

Here is a list of the features covered in this course:

• Understanding scope

• The difference between var and let

• Understanding hoisting

• The nature of objects in JavaScript

• Higher order function in JavaScript

• Callbacks

• Immediately invoked function expressions (IIFEs)

• Understanding closure

• The module pattern

• Understanding this

• Understanding and using promises

These topics are critical to JavaScript. If you don’t completely understand any of these topics or need to brush up on a few of them, this course if for you.

This course will also provide you with the code files used in the lectures so you can work with that code on your own. A total of 4 quiz are also included to help you review the concepts taught.
