Learn about destructing, iterables, generators, helpful browser APIs. The book covers concepts like higher-order functions, memoization, currying, and state machines. You will find the fundamentals of Flux and Redux and see how patterns like singleton and publisher/subscriber work.
Every topic comes with a profound explanation, code samples, and illustration. The author spent a year crafting each of the chapters to make your learning experience smooth and enjoyable.
The book is targeting intermediate developers that already have experience with JavaScript
Unfortunately, it failed to provide new (and interesting) information at least for me. (Given the price I hoped to learn at least 1-2 new things) It is great for beginners and yet again fails to give the in-depth details needed for juniors to become better developers, with a better understanding of why things work the way they do. Adding 2-3 sentences on each "story" I think would have made a huge difference in that direction.
