All of JavaScript's newest features, in depth, made easy to understand
JavaScript is a rapidly changing language and it can be challenging for experienced developers to keep up with all the new toys being added. This book explores the newest features of the world's most popular programming language while also showing readers how to track what's coming next. After setting the stage by covering who manages the process of improving JavaScript, how new features get introduced, terminology, and a high-level overview of new features, it details each new or updated item in depth, with example uses, possible pitfalls, and expert recommendations for updating old habits in light of new features.
JavaScript: The New Toys:
- Covers all the additions to JavaScript in ES2015-ES2020 plus a preview of what's coming next
- Explores the latest syntax: nullish coalescing, optional chaining, let and const, class syntax, private methods, private fields, new.target, numeric separators, BigInt, destructuring, default parameters, arrow functions, async functions, await, generator functions, ... (rest and spread), template literals, binary and octal literals, ** (exponentiation), computed property/method names, for-of, for-await-of, shorthand properties, and more
- Details the new features and patterns: modules, promises, iteration, generators, Symbol, Proxy, reflection, typed arrays, Atomics, shared memory, WeakMap, and WeakSet to name just a few
- Highlights common pitfalls and explains how to avoid them
- Shows how to follow - and participate in - the improvements process
- Explains how to use new features even before they're widely supported
Wrox Professional guides are written by working developers to address everyday needs. They provide examples, practical solutions, and expert education in new technologies, all designed to help experienced programmers do a better job.

As I said, the organization of the book is superb, with great consistency in typography to indicate the hierarchy of chapter content. The examples are clear and well-explained. There are consistent footnotes referencing Internet published standards, which is very helpful. There is advice on when new features should and should not be used. In fact there's good advice about a variety of things.
Mr Crowder is a long-time participant on the Stack Overflow question/answer website. My first exposure to him was about 10 years ago, when I (a moderately advanced, at the time, JavaScript coder) asked a question to which I expected no good answer. Mr Crowder almost immediately noticed the question and provided a brilliant solution that I continue to use to this day. His answers are, at least to me, famously thorough, thoughtful, and considerate on a site with a huge majority of very inexperienced programmers asking basic questions.
If you're a JavaScript programmer who's been "stuck" with dealing with the old language features for compatibility reasons, this is a single-stop resource for pretty much everything you'd want to know. Yes, all these things are documented somewhere on the Internet, but the appeal of the book is that it thoroughly illuminates all the things that you don't know you want to know. I don't buy many programming books, but this one was definitely a good purchase. Highly recommended.
