Learn ECMAScript 6 inside and out

About the Bundle

For any technology, it helps to get multiple points of view on the functionality to get the best possible understanding. For ECMAScript 6/2015, no two resources are recommended more frequently than Exploring ES6 by Dr. Axel Rauschmayer and Understanding ECMAScript 6 by Nicholas C. Zakas. These two points of view, investigating the specification and giving concise overviews of language features, respectively, give you the background you need to feel confident in deploying ECMAScript 6 code in your project. 

Both books are works-in-progress, continually being updated with fixes, clarifications, and more information.

ECMAScript 6 represents the biggest change to the core of JavaScript in the history of the language. Not only does the sixth edition add new object types, but also new syntax and exciting new capabilities. The result of years of study and debate, ECMAScript 6 reached feature complete status in 2014. While it will take a bit of time before all JavaScript environments support ECMAScript 6, it's still useful to understand what's coming and which features are available already.

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.

What you'll learn:

  • All of the changes to the language since ECMAScript 5
  • How the new class syntax relates to more familiar JavaScript concepts
  • Why iterators and generators are useful
  • How arrow functions are differ from regular functions
  • Additional options for storing data using sets, maps, and more
  • The power of inheriting from native types
  • Why people are so excited about promises for asynchronous programming
  • How modules will change the way you organize code

This book is being developed in the open on GitHub. You can visit the project repo to see the latest updates.
