I like this course but isn't the material out of date?
Would be good to see in es6.

The same techniques are still valid today as before. ES6/ES2015 just gives you some new choices for some things. You can do some things differently, but you could just as easily choose to do them the same way.
Also, there is a separate workshop available for Working with the Fetch API.
