Description of  50 shades of JavaScript: 50 of the most interesting features, concepts, and patterns in JavaScript.

The 50 stories in this book are a collection of the most interesting and important features, concepts, and patterns in JavaScript. From topics like destructing, iterables, and generators through helpful browser APIs, you will level up your JavaScript skills. The book covers concepts like higher-order functions, memoization, currying, and state machines. You will learn the fundamentals of Flux and Redux and see how patterns like singleton and publisher/subscriber work. Every single 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.
