Video Description

In this course, you will get JavaScript challenges that you need to solve. Each challenge consists of the task and solution. In some cases, you will be asked to fix existing code; in other cases, you will need to write some additional code. The instructor will explain each line of the solution and you will deeply understand what happens behind the scenes. Topics of the challenges include the following:

Destructuring
Array helper methods
Variables hoisting
Let, var, and const
Rest and spread operators
The ternary operator
Default parameters
Closures
IIFEs (Immediately Invoked Function Expressions)
Classes

At the beginning of the course, you will get source files for all challenges. They include start and finish states for each challenge. You need to begin with "start" folder for each challenge.

Style and Approach

This course is a great introduction to JavaScript and ES6 challenges. The instructor covers most of the related topics in a short time span to keep you interested till the end. You will perform all the tasks the same way and will get a lot of challenges to solve yourself. We discuss the solution to each challenge together.
