Get up to date on the latest ways to use JavaScript in web development

If you want to achieve JavaScript's full potential, it is critical to understand its nature, history, and limitations. To that end, this updated version of the bestseller by veteran author and JavaScript guru Nicholas C. Zakas covers JavaScript from its very beginning to the present-day incarnations including the DOM, Ajax, and HTML5. Zakas shows you how to extend this powerful language to meet specific needs and create dynamic user interfaces for the web that blur the line between desktop and internet. By the end of the book, you'll have a strong understanding of the significant advances in web development as they relate to JavaScript so that you can apply them to your next website.

Professional JavaScript for Web Developers:

  • Offers a detailed discussion of the components that make up a JavaScript implementation

  • Zeroes in on new and emerging APIs such as the Selectors API, Web Workers, and Cross-Document Messaging

  • Explores object-oriented programming in JavaScript

  • Shows how to implement drag and drop file upload with Ajax and the File API

  • Highlights the new core language features introduced in ECMAScript5

  • Explains how to work with data formats such as XML and JSON

  • Looks at what's coming in ECMAScript Harmony

  • Walks you through creating offline-capable web applications

There is a line from Lion King where little Simba comments on his Uncle Scar's weirdness. Scar replies "You have no idea."

The main point of this review is that Javascript is a really weird contraption, and that this book points this out in a way that is very helpful for programmers coming from more traditional compiled programming languages.

I have programmed in C, C++, Java, C# for many years. I have read other books on Javascript which tried to teach by examples. With normal programming languages, this works fine. However, within a few hours with this book I realized that to understand Javascript, you must give up on some basic expectations you may have as a code developer. This was a surprise to me, but crucial to be able to learn Javascript well enough to work on non-trivial projects with existing code.

Javascript is simply bizarre. There are many different ways to implement object-oriented patterns which all use different-looking code, and have subtle differences, making it so easy to get bitten by unintended consequences. From this book I learned that there is no one solid way to implement the basic pattern of your code, you must make a choice.

If you try to read a Javascript book which teaches by examples, you will be in trouble when you actually start to modify someone else's Javascript code which used a different pattern. This book doesn't just show trivial examples, it methodically goes through how it works in enough detail so you can understand how it is working under the hood.

Also, the text has plenty of warnings about buggy implementations and common pitfalls.

I usually get turned of by books this big as I assume they are badly edited. However, before this I read many books on JavaScript and while I learnt a lot from each one I never quite got my head around the more complicated parts of the language such as inheritance until reading this book. Zaka's just explains everything really well, though don't interpret that as meaning at length, I think his chapters are more the natural length of the topics they describe. Not condensed down to 'seem' friendly as in "The Good Parts".
This is the book which finally got me comfortable with the core language, though it also taught me a lot which I didn't expect to be taught or hadn't even heard of such as document fragments and many aspects of the browser API's. So while this book could have been a lot shorter by removing a lot of the stuff most people won't care about, I am glad the author kept them in as I found them interesting. Actually I wish the book was longer. And besides its well enough organised that you could simply skip to 'the good parts' and still end up with a better book than its restricted cousins.

If you have already read the previous edition of this book, the reading of this third edition will bring you a lot of new stuffs. This book is not only a complete rewriting, but also a more deep explanation and a detailed presentation of HTML5 apis.
For me, "JavaScript for Web Developpers" is really really more user friendly than "Javascript, the definitive guide". Code samples are easy to understand (and don't spread across 3 or 4 pages). The style is simple and the writing is easily understood by a "non english native" like me.
The only thing I would change if I could is stripping out the 50 pages on XML and replacing them by more of advanced techniques.
Definitly a must-have.

This book is NOT for most beginners, but maybe for beginners with other coding experience or with a natural knack for logic, scripting, and coding type exercises. Otherwise, advanced coders of most any language, or intermediate to advanced JavaScript developers will find this book very useful.

I am a self taught JavaScript coder, with about seven years of experience. Before studying this book, I was already writing some relatively complicated code, including functions, constructors, methods on constructors, jQuery add-ons, and more. This book took my existing JavaScript knowledgebase and cleared it up, fixed some existing misconceptions I had regarding JavaScript, taught me industry standard practices/naming conventions/coding practices/etc. that I had not already picked up on, and then it took my skills to the next level by covering topics I had a loose understanding of at best.

After going through this book in its entirety (twice for good measure :) ...), I can truly say that I am a more efficient, cleaner, and certainly more sophisticated JavaScript developer. I highly recommend this book for anyone looking to learn the latest ECMA 5.x has to offer (I previously coded to ECMA-262 version 3 based JavaScript only), those looking to learn advanced JavaScript coding skills, and/or those looking to refine their existing skillset to reflect the latest best industry practices used when coding in JavaScript.

This book is about so much more than Javascript, its a huge encyclopedia of everything related to modern-day web development techniques.
It does an excellent job of describing Javascript, with a lengthy section on OO techniques (describing the pros and cons of dynamic prototyping, parasitic construction, durable construction, prototype chaining, constructor chaining parasitic combination inheritance, and so on, to name a few).
Then it has full descriptions of all web related technologies such as BOM, DOM, AJAX, COMET, JSON, XML,HTML5, event handling, and much much more. Each of these topics is covered in depth and clearly explained.
The book also contains a substantial amount of history describing the evolution of the web, which is essential to provide context to understand where the web is today, how it got here and how the legacy of the past still echoes today.

If you have any involvement in web technologies, direct or tangentially, or you have no involvement in them but are curious and want to learn about them, then this is a must read.
