JavaScript: The Definitive Guide: Activate Your Web Pages

By David Flanagan

~150 reviews

Since 1996, JavaScript: The Definitive Guide has been the bible for JavaScript programmers—a programmer's guide and comprehensive reference to the core language and to the client-side JavaScript APIs defined by web browsers.

The 6th edition covers HTML5 and ECMAScript 5. Many chapters have been completely rewritten to bring them in line with today's best web development practices. New chapters in this edition document jQuery and server side JavaScript. It's recommended for experienced programmers who want to learn the programming language of the Web, and for current JavaScript programmers who want to master it.

"A must-have reference for expert JavaScript programmers...well-organized and detailed." —Brendan Eich, creator of JavaScript, CTO of Mozilla

"I made a career of what I learned from JavaScript: The Definitive Guide.” —Andrew Hedges, Tapulous


  • Highly recommended by developers
  • Provides in-depth atomic-level knowledge of JavaScript (1000+ pages)
  • Possibly the most definite JavaScript book out there


  • Not recommended for beginner
  • Not enough code samples
  • This book is very dense, not for the faint-hearted

Top Tech Book Review

Warning, this book is not for beginner if you have no experience in coding. If you are someone who strives to deeply understanding how JavaScript and its inner working, then this book is for you. The book is dense, over 1000+ pages, but it is not fluff. The book is packed with heavy content with detailed explanation on complex concepts.

This book will probably be next to your computer for years to come as reference material. Most developers who purchased previous edition of the book are most likely to buy future editions. This goes to show how the author and its knowledge stood the test of time and quality of his work.

Again, not recommended for beginners, but if you're in the industry and your career has been stagnant for awhile, this book might help you propel to the next level of your career.
