JavaScript is the programming language of the web and is used by more software developers today than any other programming language. For nearly 25 years this best seller has been the go-to guide for JavaScript programmers. The seventh edition is fully updated to cover the 2020 version of JavaScript, and new chapters cover classes, modules, iterators, generators, Promises, async/await, and metaprogramming. You’ll find illuminating and engaging example code throughout.
This book is for programmers who want to learn JavaScript and for web developers who want to take their understanding and mastery to the next level. It begins by explaining the JavaScript language itself, in detail, from the bottom up. It then builds on that foundation to cover the web platform and Node.js.
Topics include:
- Types, values, variables, expressions, operators, statements, objects, and arrays
- Functions, classes, modules, iterators, generators, Promises, and async/await
- JavaScript’s standard library: data structures, regular expressions, JSON, i18n, etc.
- The web platform: documents, components, graphics, networking, storage, and threads
- Node.js: buffers, files, streams, threads, child processes, web clients, and web servers
- Tools and language extensions that professional JavaScript developers rely on.
The overwhelming majority of websites use JavaScript, and all modern web browsers—on desktops, tablets, and phones—include JavaScript interpreters, making JavaScript the most-deployed programming language in history. Over the last decade, Node.js has enabled JavaScript programming outside of web browsers, and the dramatic success of Node means that JavaScript is now also the most-used programming language among software developers. Whether you’re starting from scratch or are already using JavaScript professionally, this book will help you master the language.
If you are already familiar with other programming languages, it may help you to know that JavaScript is a high-level, dynamic, interpreted programming language that is well-suited to object-oriented and functional programming styles. JavaScript’s variables are untyped. Its syntax is loosely based on Java, but the languages are otherwise unrelated.
JavaScript derives its first-class functions from Scheme and its prototype-based inheritance from the little-known language Self. But you do not need to know any of those languages, or be familiar with those terms, to use this book and learn JavaScript.
