Understanding ECMAScript 6: The Definitive Guide for JavaScript Developers

This book is a guide for the transition between ECMAScript 5 and 6. It is not specific to any JavaScript environment, so it is equally useful to web developers as it is Node.js developers.

This book is intended as a guide for those who are already familiar with JavaScript and ECMAScript 5. While a deep understanding of the language isn't necessary to use this book, it is helpful in understanding the differences between ECMAScript 5 and 6. In particular, this book is aimed at intermediate-to-advanced JavaScript developers (both browser and Node.js environments) who want to learn about the future of the language.

This book is not for beginners who have never written JavaScript. You will need to have a good basic understanding of the language to make use of this book. You'll learn:

How ECMAScript 6 class syntax relates to more familiar JavaScript conceptsWhat makes iterators and generators usefulHow arrow functions differ from regular functionsWays to store data with sets, maps, and moreThe power of inheritanceHow to improve asynchronous programming with promisesHow modules change the way you organize code

Whether you're a web developer or a Node.js developer, you'll find this book indispensable on your journey from ECMAScript 5 to ECMAScript 6.
