WHAT THIS BOOK COVERS
Professional JavaScript for Web Developers, 4th Edition, provides a developer-level introduction, along with the more advanced and useful features of JavaScript.
The book begins with an exploration of how JavaScript originated and evolved into what it is today. A detailed discussion of the components that make up a JavaScript implementation follows, with specific focus on standards such as ECMAScript and the Document Object Model (DOM).
Building on that base, the book moves on to cover basic concepts of JavaScript, including classes, promises, iterators, and proxies. This is followed by an in-depth examination of client detection, events, animations, forms, errors, and JSON.
The last part of the book is focused on the newest and most important specifications that have emerged in the past few years. This includes fetch, modules, web workers, service workers, and a collection of emerging APIs.
