Course Description

This is the tutorial you've been looking for to master ES6 Javascript.

Generators? We got it. Arrow Functions? Of course. Rest/Spread Operator? Included! And every other new piece of syntax!

Mastering ES6 syntax can get you a position in web development or help you build that personal project you've been dreaming of. It's a skill that will put you more in demand in the modern web development industry, especially with the release of modern web frameworks like React and Angular 2.

This course will get you up and running quickly, and teach you the core knowledge you need to deeply understand and build applications using each new piece of Javascript syntax introduced with ES6.

We'll start by mastering the fundamentals of iteration over Arrays using helpers like 'forEach', 'map', and 'reduce'.  After an introduction to Array helpers, we'll dive right in to advanced ES6, covering topics like enhanced object literals, default function arguments, and classes.  Every topic includes multiple live code exercises to ensure you understand each new concept.

If you are new to Javascript or ES6, or if you've been working to learn it but sometimes feel like you still don't quite 'get it', this is the Javascript course for you! To learn ES6 you have to understand it and comprehend exactly why each piece of syntax was added to the language

  • Learn the purpose of Babel and why ES6 was created
  • Master the process of refactoring your current ES5 code into super-charged ES6
  • Grasp the difference between the 'rest' and 'spread' operators
  • Develop complex applications that scale in complexity by mastering advanced ES6 design patterns
  • Dive deeper into iteration using generators.  No fancy terms required!

I've built the course that I would have wanted to take when I was learning ES6. A course that explains the concepts and how they're implemented in the best order for you to learn and deeply understand them.

Gives a good segway into getting the groundwork for ES6 Javascript, which can be pretty quirky! I enjoyed taking this course and learnt a ton of stuff!

By Jerzy Kedra on 11/7/2019

Great content on JS fundamentals. However with more advanced topics explanations are not clear and examples not great. Particularly weak topics was the one on generators. Could be much better.

By David Arcos on 8/29/2019

I love the way that Mr.Grider explains stuff, he's great! But, I was a bit disappointed with the fact that I did not have the answers to the quizzes directly from him, or that he went over the problems to solve them and I had to rely on other students postings which sometimes got results using formulas not yet explained. Otherwise, I think the course was great. Thank you.

I am a java developer that recently jumped head in first developing an angular app. I felt as if I all the time was writing too much complicated code to achieve simple things, this course has taught me that I indeed did things wrong and now I have learned a better more concise way to program. Great stuff!!!

The course filled a couple of holes in my ES6 feature awareness, and otherwise solidified my understanding. I'm glad that I've reviewed ES6 via this course. Many Thanks! Unfortunately, regarding asynchronous code, the course title indicates this is about ES6 features. I find myself wishing there was further instruction--in the same style--on post ES6 features, namely async/await.

Stephen is a great teacher. I like the way he illustrates the concepts using diagrams, then applies those concepts in code. Certain concepts are missing in the course. For e.g. symbols, sets, maps, modules, iteration and iterable protocols are missing. It would be of great help if these are included in the course.

By Chris McAnally on 9/30/2017

Fairly knowledgeable, good at explaining, missed a couple of minor issues such as the scoping issues of let vs var. Not mentioning how let is scoped differently is really a small, but important oversight.

one of the best courses ive taken on udemy. teacher is super descriptive. goes slowly enough for newbies. VISUAL TEACHER! this is a big plus for me. he teaches with charts, highlights what hes talking about. only reasons i gave 4.5 and not a 5, is that the challenges are not always clear what he wants from the student. and also he doesnt supply the correct answer, so you have to go through all the students answers and try to decide for yourself which is correct. other than that, super course!

By David Ladowitz on 12/28/2016

Stephens courses are always great. This is the third course I've taken from him. He has very clear examples and exercises to work through. This course is a great complement to the React courses he has. I kinda wish I had take this one first though. Honestly possibly the best instructor I've found on Udemy.

By Amandeep Singh on 8/30/2016

very useful course by an excellent instructor. I love taking course from Stephen Grider. Love him for these courses and helping me gain this invaluable knowledge and skills. And I just can't express myself in words how much I love. I have taken courses from other instructors on udemy, but there is no match for Stephen. He is the BEST. Thank you very much.
