AdvancED DOM Scripting: Dynamic Web Design Techniques ReviewUPDATE (3-17-08)
I bought this book again because the material is definitely good. I'm really bummed Friends Of Ed let it go to press with all these errors though. I mean, come on--I'm finding errors all over the place! That is a great disservice to Sambells. But I've decided the material is worth wading through the many, many copy editing oversights. I'm crossing my fingers I don't get stuck troubleshooting typos in the code that choke my browser. That could easily waste hours of my time.
-=-=-
I was pretty excited after I dropped the $50 or so to by this book because the contents are right down my alley. Unfortunately, I could hardly make it out of Chapter 1 for all the typos and editorial oversights. Here are a few as an example:
PG 34 -- "myVarialbe" instead of "myVariable"
PG 35 -- "when you retrieving" instead of "when you are retrieving"
PG 36 -- references a function called "initAchors()" that isn't used in the example code for that example. initAnchors() appears in the next example on the next page.
PG 37 -- number of iterations in loop changes from 3 to 5 from 1st example to 2nd example for no apparent reason - this is confusing and distracts from the point being made.
PG 37 -- Figure 1-7 shows three objects in diagram instead of the 5 needed (one for each loop)
This is all in just 3 pages!
This is the part of the book I started reading first so I assume the rest of the book is going to be as poorly edited/ proofread. This surprises me as I own over 5 or 6 titles from the Friend Of Ed series and I don't recall ever seeing so much as a typo in any of them.
Overall, I think the book shows promise. But I can't tolerate errors like this in a programming book. They are difficult enough to read already without having to figure out what the message was "supposed" to be.
I'm returning this book to the store. When it reaches a later edition I may give it another go. It needs some serious "debuggin" first though.AdvancED DOM Scripting: Dynamic Web Design Techniques OverviewDOM Scripting is a vital technique for web developers and designers to learn and master in the modern web development arena, for adding dynamic effects to web applications such as animations, maps, drag and drop, and more.At friends of ED, we kick-started the interest in this subject with Jeremy Keith's acclaimed book DOM Scripting (friends of ED 1590595335.) And now, with AdvancED DOM Scripting, we're aiming to take the reader further-AdvancED DOM Scripting starts where the original DOM Scripting left off, assuming the reader has already mastered the basics, and taking them further, with countless real world tutorials. It is the first book to exclusively cover advanced DOM Scripting techniques, and reads like a wish list of must have dynamic web application features, including visual effects using JavaScript libraries, Ajax, Mashups using APIs, and much more.

JavaScript Cookbook Review§
One bit of advice if you are like me when you get a reference collection of this sort: I immediately flip through the table of contents or the index to get to whatever topic I am currently obsessing on.
In the case of this book, you may want to spend a few minutes in the oft-ignored preface. It contains some noteworthy information on the author's approach. Specifically:
"Many of the examples won't work with IE6. Before I even began the book I decided not to provide support for IE6--including any workaround code."
The author is a bit more forgiving in the case of IE7: "Where IE7 doesn't work, either I provide IE7-specific workarounds in comments in the example code you can download, or I make a note about nonsupport in the recipe--or both."
I work on teams developing browser-based applications for the real world, so IE6 is still absolutely relevant to me. In fact, the corporation for which I honestly sweat is itself "standardized" on IE6 for all employees. Even so, I still recommend this book because of the relevancy of the examples and its forward-looking approach.
The fact that the code download file is about 63 megs compressed should give an idea of how much is contained in this big store of scripting knowledge.
§JavaScript Cookbook Overview
Why reinvent the wheel every time you run into a problem with JavaScript? This cookbook is chock-full of code recipes that address common programming tasks, as well as techniques for building web apps that work in any browser. Just copy and paste the code samples into your project -- you'll get the job done faster and learn more about JavaScript in the process.

You'll also learn how to take advantage of the latest features in ECMAScript 5 and HTML5, including the new cross-domain widget communication technique, HTML5's video and audio elements, and the drawing canvas. You'll find recipes for using these features with JavaScript to build high-quality application interfaces.

Create interactive web and desktop applications
Work with JavaScript objects, such as String, Array, Number, and Math
Use JavaScript with Scalable Vector Graphics (SVG) and the canvas element
Store data in various ways, from the simple to the complex
Program the new HTML5 audio and video elements
Implement concurrent programming with Web Workers
Use and create jQuery plug-ins
Use ARIA and JavaScript to create fully accessible rich internet applications

Ajax: The Definitive Guide Review§
There is a LOT of code in this 950 page book. I guess there is something here for everyone because there is code not directly related to Ajax but is directed to HTML structure or CSS presentational aspects or to frameworks that may include Ajax conveniences.
In fact, the amount of code may interfere with the author's object of appealing to two very different types of people with this book: Web developers and project managers looking for a high-level view. Except for some intro chapters and the odd breather between 10-15 page code listings, I don't think any project managers *I* have worked with would extract much from the book.
The book has 4 sections:
Part 1 - Ajax Fundamentals: the basic technologies that could form the core of a typical Ajax application.
Part 2 - Ajax Foundations: approaches to standards-compliant structure, separation of the presentational layer and client-side behaviors. Code code code!
Part 3 - Ajax in Applications: describes the specific implementations of these technologies into Web applications. More code!
Part 4 - Wrapping Up: tips on optimization.
In addition, there are some reference appendices on XML and XSLT; on JavaScript frameworks; on Ajax implementation risks; and most interestingly, a catalog of freely available Web service APIs.
One thing I did not like about the code listings was the use of Prototype style $() function syntax. This means when I see something like:
var titleText = $('title').firstChild;
I had to check whether .firstChild was a reference to a Prototype object or a reference to the standard DOM object. If the standard object, it would have been a whole lot clear just to have written document.getElementById().
The book index is actually pretty good. With 950 pages stuffed with content, you will probably be thankful for that!
§Ajax: The Definitive Guide Overview
Is Ajax a new technology, or the same old stuff web developers have been using for years? Both, actually. This book demonstrates not only how tried-and-true web standards make Ajax possible, but how these older technologies allow you to give sites a decidedly modern Web 2.0 feel.Ajax: The Definitive Guide explains how to use standards like JavaScript, XML, CSS, and XHTML, along with the XMLHttpRequest object, to build browser-based web applications that function like desktop programs. You get a complete background on what goes into today's web sites and applications, and learn to leverage these tools along with Ajax for advanced browser searching, web services, mashups, and more. You discover how to turn a web browser and web site into a true application, and why developing with Ajax is faster, easier and cheaper. The book also explains:

How to connect server-side backend components to user interfaces in the browser
Loading and manipulating XML documents, and how to replace XML with JSON
Manipulating the Document Object Model (DOM)
Designing Ajax interfaces for usability, functionality, visualization, and accessibility
Site navigation layout, including issues with Ajax and the browser's back button
Adding life to tables & lists, navigation boxes and windows
Animation creation, interactive forms, and data validation
Search, web services and mash-ups
Applying Ajax to business communications, and creating Internet games without plug-ins
The advantages of modular coding, ways to optimize Ajax applications, and more
This book also provides references to XML and XSLT, popular JavaScript Frameworks, Libraries, and Toolkits, and various Web Service APIs. By offering web developers a much broader set of tools and options, Ajax gives developers a new way to create content on the Web, while throwing off the constraints of the past. Ajax: The Definitive Guide describes the contents of this unique toolbox in exhaustive detail, and explains how to get the most out of it.

High Performance JavaScript (Build Faster Web Application Interfaces) ReviewThis book is a good reference on how to optimize JavaScript applications and also an interesting read in case you want to know how things work "under the hood".
Many of the techniques presented also works for other programming languages (and are well-known performance tricks) and can be used without increasing too much the code complexity, which is a huge gain, you're not just becoming a better JavaScript developer but also a better developer.
One thing that should be clear is that this book is NOT intended for BEGINNERS, since it already presumes that you have a good knowledge and experience with JS programming.
If you already read Professional JavaScript for Web Developers (Wrox Programmer to Programmer) (also written by Zakas), High Performance Web Sites: Essential Knowledge for Front-End Engineers and Even Faster Web Sites: Performance Best Practices for Web Developers you will find that some of the techniques were already present on those books, so if you're up-to-date with the new technologies/tools and been researching about the subject probably you already know a good part of what this book has to teach, nevertheless it still a nice and interesting read since it explains how the JavaScript engines work and why those techniques are faster, the fact that it is concise is a big plus too.
The book has some typo mistakes (which doesn't affect the understanding) and some of the line graphs (used to show browsers benchmark) are hard to read since all the lines look the same (as of 1st Edition).
I strongly recommend this book to any intermediate to advanced developer who wants to learn how to improve the overall performance of JavaScript applications since it is a concise and accurate compilation of best practices, even if you know a lot about the subject you may learn a few new tricks or understand a little bit better why it works...High Performance JavaScript (Build Faster Web Application Interfaces) Overview
If you're like most developers, you rely heavily on JavaScript to build interactive and quick-responding web applications. The problem is that all of those lines of JavaScript code can slow down your apps. This book reveals techniques and strategies to help you eliminate performance bottlenecks during development. You'll learn how to improve execution time, downloading, interaction with the DOM, page life cycle, and more.

Yahoo! frontend engineer Nicholas C. Zakas and five other JavaScript experts -- Ross Harmes, Julien Lecomte, Steven Levithan, Stoyan Stefanov, and Matt Sweeney -- demonstrate optimal ways to load code onto a page, and offer programming tips to help your JavaScript run as efficiently and quickly as possible. You'll learn the best practices to build and deploy your files to a production environment, and tools that can help you find problems once your site goes live.

Identify problem code and use faster alternatives to accomplish the same task
Improve scripts by learning how JavaScript stores and accesses data
Implement JavaScript code so that it doesn't slow down interaction with the DOM
Use optimization techniques to improve runtime performance
Learn ways to ensure the UI is responsive at all times
Achieve faster client-server communication
Use a build system to minify files, and HTTP compression to deliver them to the browser

HTML5: Up and Running ReviewI must say: I enjoyed going through this book. It is written in an opinionated and slightly irreverent style, so I found it a mildly amusing read.
That being said: why do people buy a book on HTML5? Some would like to have a good in-depth reference on the ins and outs of the new language. Well now - that's not this book. Others might be new to web development and think learning HTML5 would be a good starting point. While they are right that HTML (5 or 4) is the place to start, this book surely isn't.
There's some depth when it comes to background, but much less when it comes to HTML5 itself or how to use it. True, the tag and geolocation are covered pretty much in detail, but the author made some hard to defend choices in spending his paper estate.
HTML5 gives us no more than a handful of new tags, still some of those ( and , for example) are simply mentioned once and that's that. No examples, no advise on where to use them, nothing on browser support. Yet the book takes five pages at the start to tell the story of how the img-tag came into being some 15 years ago. Again, mildly amusing, but probably not the reason you are thinking of buying this book.
Another example: there are 10 pages with a primer on audio and video codecs, plus another 19 (!) detailed pages (with lots of screen shots) on how to use a number of specific and probably soon outdated software tools to encode video for the web. All fine for those who are completely new to video encoding and believe a book on HTML5 should be the starting point for that. But when it comes to the actual tag (under the aptly named heading "At Last, the Markup"), this consists of a meager 3 pages that include a statement like this:
"The element has methods like play() and pause()".
Huh? "Methods like"? So which other methods are there? And how and where would I use them? Are these standardized across browsers? Where can I find more about them? Any example, maybe?
If you think these are the kind of questions a book on HTML5 should answer, you are out of luck. The above sentence is all the information on this particular topic you are going to get. Not a word about implementing these methods, or on how to style the browsers' native video controllers that come with HTML5 support. There are a good number of external references for information on things like Unicode, codecs and video containers, and some useful scripts, but not a word on how we can get the information on how to control and style the tag. Maybe the logical conclusion would be: in another book on HTML5, perhaps?HTML5: Up and Running Overview
If you don't know about the new features available in HTML5, now's the time to find out. The latest version of this markup language is going to significantly change the way you develop web applications, and this book provides your first real look at HTML5's new elements and attributes.

Even though work on HTML5 is ongoing, browsers such as Safari, Mozilla, Opera, and Chrome already support many of its features -- and browsers for smart phones are even farther ahead, especially iPhone's MobileSafari browser. With HTML5: Up & Running, you'll learn how this new version enables browsers to interact with JavaScript much more easily than before. You'll also learn how HTML5 can help you develop applications that:

Display video directly in the browser, without having to rely on plugins
Work even when a user is offline, by taking advantage of HTML5's persistent storage
Offer a drawing canvas for dynamically generated 2-D graphics

This concise guide is the most complete and authoritative book you'll find on the subject. Author Mark Pilgrim writes the weekly digest for the HTML5 Working Group, and represents Google at conferences on HTML5's capabilities. Stay ahead of the curve. Order a copy of this book today.

Closure: The Definitive Guide ReviewI read Closure: The Definitive Guide as part of O'Reilly's rough cuts program, and I can honestly say that the book is one of the best technical books I've read in quite some time. It's clear that the author sought to leave no stone unturned in writing this book; he succeeded brilliantly. His writing style is concise but not at all confusing, leading to a great book that lends itself just as well to sit-down reading as it does a reference guide.
This book is definitely targeted towards developers, not managers. You should have at least some experience with JavaScript and the DOM before reading this. The author thankfully doesn't rehash the basics of such material before digging into Closure, but he also doesn't make the assumption that you need to have written a book on JavaScript in order to understand how to use everything. After you read the introduction chapter, you can safely skip some parts and come back to them later as you begin to understand Closure's design patterns. I thoroughly read most chapters and just skimmed others, which was great because it let me get familiar with the material without getting bogged down in all the details present in such an immense SDK.
Closure is most likely overkill if you're just building one-off websites, but if you want to build something more, do yourself a favor and buy this book and read it. Don't sell yourself short. Otherwise you'll be doomed to blindly throwing jQuery, MooTools, Prototype, or the like onto your canvas and hoping it'll work just as well for your large app -- it won't. Soon after you begin developing with Closure and reading this book, you'll experience the joy and relief that only a proper JavaScript TOOLKIT can provide.
Overall, this is a really great book that I wouldn't hesitate to recommend to any front-end developer who is tasked with building a web application that they want to be fast, browser-agnostic, and bug free.Closure: The Definitive Guide Overview
If you're ready to use Closure to build rich web applications with JavaScript, this hands-on guide has precisely what you need to learn this suite of tools in depth. Closure makes it easy for experienced JavaScript developers to write and maintain large and complex codebases -- as Google has demonstrated by using Closure with Gmail, Google Docs, and Google Maps.

Author and Closure contributor Michael Bolin has included numerous code examples and best practices, as well as valuable information not available publicly until now. You'll learn all about Closure's Library, Compiler, Templates, testing framework, and Inspector -- including how to minify JavaScript code with the Compiler, and why the combination of the Compiler and the Library is what sets Closure apart from other JavaScript toolkits.

Learn how the Compiler significantly reduces the amount of JavaScript users have to download when visiting your site
Discover several ways to use the Compiler as part of your build process
Learn about type expressions, primitives, and common utilities
Understand how Closure emulates classes and class-based inheritance
Use Closure Templates on the server and the client from either JavaScript or Java
Test and debug your JavaScript code, even when it's compiled
