“Eloquent Javascript 3rd Edition is a worthy and much-needed update to the popular programming book. The fact that the book covers ES6 is worth a re-read, but the new edition goes above and beyond with new illustrations, a new exercise, and tighter writing. The 3rd edition of the book is substantially improved from its predecessors and worthy of the hype.”—Books on Code"It’s a smart, lean JavaScript tutorial that exists as an in-print book from No Starch Press, and a free, nicely formatted web version . . . easily the most enjoyable read in this list. And there are so many useful insights that you won’t be bored."—Matthew MacDonald, Medium's Young Coder“This is all the JavaScript knowledge you’ll need to hit the ground running in a JavaScript project . . . it’s a book I will be frequently revisiting as it has put JavaScript back on my radar.”—GeekTechStuff“This book would make a great addition to any developer's reference books . . . I really like the author's style of writing and clarity of explanations. The sample code and exercises also work, which can be a rare feature in tech-related books”—Gary Woodfine, Software Developer“I think this is one of the most enjoyable programming books I’ve read. It covers the core features of the language concisely but then goes on to illustrate how to use those features.”—Ian Hopkinson, IanHopkinson.org“If you’re at all interested in learning JavaScript, making this your first guide could mean the difference between getting discouraged and giving up and really getting into programming as a lifelong venture.”—Joshua Johnson, Design Shack“Marijn Haverbeke is a software philosopher and all-round genius. He also has a terrific sense of humor and writes both prose and code in a friendly and un-intimidating fashion. In common with the very best teachers he dispenses his wisdom with disarming simplicity. I became a better architect, author, mentor and developer because of this book. It deserves to share shelf space with Flannagan and Crockford.”—Angus Croll, Javascript We Blog"A tour de force that takes you from the fundamentals to the heights of JavaScript mastery. Marijn Haverbeke’s conversational prose breathes life into JavaScript, making it accessible and engaging."—Alex Maher, .NET C# dev"The author, Marijn Haverbeke, has a great voice."—Abu Sayed, Sayed.Cyou Blog"One of the things that makes [Eloquent JavaScript, 3rd Edition] so good is that it doesn’t shy away from complexity . . . Haverbeke is a talented teacher, and he seems to have an intuitive understanding of how difficult concepts can be explained without oversimplifying them."—Neil Abad, Book Review Buffs
