JavaScript Next: Your Complete Guide to the New Features Introduced in JavaScript, Starting from ES6 to ES9

by Raju Gandhi

Overview

JavaScript has finally grown up. Armed with a slew of new features, JavaScript now makes writing the code that powers your applications elegant, concise, and easy to understand. This book is a pragmatic guide to the new features introduced in JavaScript, starting with Edition 6 of ECMAScript, and ending with Edition 9.

Using a "compare and contrast" approach, each chapter offers a deep dive into new features, highlighting how best to use them moving forward. As you progress through the book, you'll be offered multiple opportunities to see the new features in action, and in concert with one another.

Backed by an example-driven writing style, you'll learn by doing, and get ready to embrace the new world of JavaScript.

About the Author

Raju Gandhi is a programmer with over 15 years of experience in the software industry. He believes that the key to writing software that our users will cherish lies in having a keen understanding of the problem, and the tools available to solve those problems. He has been a core speaker on the No Fluff, Just Stuff symposium series for over 6 years, along with other conferences like DevNexus, Connect.Tech and GIDS, India. In both his careers as a software developer and teacher, he believes the key is to keep things simple, and in the words of Rich Hickey, "de-complected". This approach seems to scale well, for both maintainable software, and happy audience members.
