Unlike many other courses, you will not only learn the main features of ES6, but you will also know when to use them. After all, knowing generator functions or promises won’t bring you forward. Discovering how to use lazy evaluation and how to call an API GET request elegantly will make a difference for you.
The course focuses on practical use cases and exercises. After a short, concise summary, you will get a chance to solve some exercises, and check my reference solutions.
ES6 in Practice is not only about ES6. As a side-effect, you will boost your problem solving skills by tackling meaningful problems in practice.
