Learn ECMAScript - Second Edition: Discover the latest ECMAScript features in order to write cleaner code and learn the fundamentals of JavaScript (學習 ECMAScript（第二版）：探索最新的 ECMAScript 特性，以撰寫更乾淨的程式碼並學習 JavaScript 的基本原理)

Get up and running with all the new features of ECMAScript and explore new ways of coding with JavaScript.

Key Features

• Grasp the latest features of ECMAScript and the best way to use it in production code
• Learn newly added native APIs to JS Engine and perform tasks efficiently with a cleaner code base
• Understand the more complex sides of JavaScript such as the inheritance model, low-level memory management, multithreaded environments, and web workers

Book Description

Learn ECMAScript explores implementation of the latest ECMAScript features to add to your developer toolbox, helping you to progress to an advanced level. Learn to add 1 to a variable andsafely access shared memory data within multiple threads to avoid race conditions.

You'll start the book by building on your existing knowledge of JavaScript, covering performing arithmetic operations, using arrow functions and dealing with closures. Next, you will grasp the most commonly used ECMAScript skills such as reflection, proxies, and classes. Furthermore, you'll learn modularizing the JS code base, implementing JS on the web and how the modern HTML5 + JS APIs provide power to developers on the web. Finally, you will learn the deeper parts of the language, which include making JavaScript multithreaded with dedicated and shared web workers, memory management, shared memory, and atomics. It doesn't end here; this book is 100% compatible with ES.Next.

By the end of this book, you'll have fully mastered all the features of ECMAScript!
