Kurzbeschreibung

This book provides a developer-level introduction along with more advanced and useful features of JavaScript. Coverage includes:

  • JavaScript use with HTML to create dynamic webpages, language concepts including syntax and flow control statements
  • variable handling given their loosely typed nature
  • built-in reference types such as object and array
  • object-oriented programing
  • powerful aspects of function expressions
  • Browser Object Model allowing interaction with the browser itself
  • detecting the client and its capabilities
  • Document Object Model (DOM) objects available in DOM Level 1
  • how DOM Levels 2 and 3 augmented the DOM
  • events, legacy support, and how the DOM redefined how events should work
  • enhancing form interactions and working around browser limitations
  • using the tag to create on-the-fly graphics
  • JavaScript API changes in HTML5
  • how browsers handle JavaScript errors and error handling
  • features of JavaScript used to read and manipulate XML data
  • the JSON data format as an alternative to XML
  • Ajax techniques including the use of XMLHttpRequest object and CORS
  • complex patterns including function currying, partial function application, and dynamic functions
  • offline detection and storing data on the client machine
  • techniques for JavaScript in an enterprise environment for better maintainability

This book is aimed at three groups of readers: Experienced object-oriented programming developers looking to learn JavaScript as it relates to traditional OO languages such as Java and C++; Web application developers attempting to enhance site usability; novice JavaScript developers.

Nicholas C. Zakas worked with the Web for over a decade. He has worked on corporate intranet applications used by some of the largest companies in the world and large-scale consumer websites such as MyYahoo! and the Yahoo! homepage. He regularly gives talks at companies and conferences regarding front-end best practices and new technology.

5.0 von 5 Sternen Coming from a real language? This book is your best bet. 3. November 2012
Von Kevin Stokes - Veröffentlicht auf Amazon.com
Format:Kindle Edition|Verifizierter Kauf
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. After you get about 1/4 of the way through it you will be wondering how any Javascript code runs on Internet Explorer at all, since about every other page is another 'this-is-broken-in-IE' warning boxes.

The text is written in a very clear style, never glossing over anything. It isn't at all cute or made to be entertaining, just kind of down to business.

There is no question I will be using this book nearly every time I have to work on Javascript code.

If you are just looking to make a little mouse button handler in a web page, this is probably not the book for you. It does not jump right into little useful examples.

If you are coming from a programming background in traditional compiled languages, and you want to know more about Javascript than little tiny scripts, IMHO this book is absolutely necessary. You will never regret purchasing it.

5.0 von 5 Sternen User friendly 20. März 2012
Von Francois Piat - Veröffentlicht auf Amazon.com
Format:Taschenbuch|Verifizierter Kauf
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.

5.0 von 5 Sternen Long but so is the topic 19. März 2012
Von J Rosoman - Veröffentlicht auf Amazon.com
Format:Taschenbuch
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.

5.0 von 5 Sternen Fantastic encyclopedia of not just Javascript but web development in general 22. Mai 2012
Von Hotcheese - Veröffentlicht auf Amazon.com
Format:Taschenbuch|Verifizierter Kauf
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.

5.0 von 5 Sternen Level Up 22. Mai 2012
Von Marty Hines - Veröffentlicht auf Amazon.com
Format:Taschenbuch|Verifizierter Kauf
Professional JavaScript for Web Developers is a deep dive into the JavaScript programming language. It also covers, in great detail, things such as - the DOM, the BOM, OOP, Ajax, JSON, Canvas ... the list goes on.

If you want to become an expert in JavaScript, this is the book for you.

Nicholas Zakas has a real knack for getting the knowledge from his brain into yours. He does so by first giving a detailed explanation of a subject, followed by a short snippet of relevant code, and finally he explains the code.
If you find yourself unsure of a particular concept, trudge along, it will be explained.

I highly recommend you buy this book. It's easily the best book I've read on the subject.
