This course will teach you the fundamentals of ES6 in the JavaScript programming language.

There is a lot of content out there for learning ES6 but much of this doesn’t teach the why behind the concepts. Through code examples this course will teach you all the ES6 fundamentals and show you how things were done before. By doing this you will be able to confidently work with and update older projects.

Understanding ES6 is a skill that will help you gain employment in the industry today. It is also very fun to work with! If you ware looking to work with libraries such as React then it is a fundamental skill and part of your learning journey.

Taking this course will allow you to be quickly immersed in the syntax and be up and running with ES6 quickly. I use visual examples and apply the concepts to real day to day like so you can recall the knowledge quickly.

We will cover the basics such as using let and const and for…of and for…in loops. We will then go on to look at topics such as destructuring and using the spread operator. We will then look at array helper methods to stop writing loops and understand how to use ES6 classes. We will end the course by looking at promises.

Through fun and concise videos and code examples followed up with code challenges you will complete the course feeling confident to go off and write ES6 on your own.

Whether you are relatively new to programming, JavaScript or you just want to build upon some existing knowledge this course will help provide you with a toolbox to becoming a better developer.
