Learning jQuery
hal10001 writes "One complaint of just about any book that attempts to teach a new language or technology is a presumed level of expertise by the authors. I found it refreshing that in Learning jQuery the book begins... well, at the beginning, and increases in difficulty along with the concepts. It gives designers and entry-level interface developers the opportunity to come up to speed at an acceptable pace."Read below for the rest of Brian's thoughts on the book.

summary
Better Interaction Design and Web Development with Simple JavaScript Techniques
While I consider the screenshots to be lacking in quality, overall, this book will definitely leave you satisfied. The essentials required to be successful at developing with jQuery are all touched upon, and the depth of explanation for each piece of code is precise and clear. You will not find yourself flipping through chapters of fluff, added only to beef up the number of pages. Each tutorial and example is carefully planned and executed.
Describing concepts in relation to any JavaScript library can be difficult. Since libraries are in fact JavaScript, it can be easy to confuse beginners. The authors are careful not to allow this to happen. This is especially apparent in Chapter 3, when highlighting the event model, event capturing and event bubbling. A clear distinction is made between browser implementations and the unique facets of jQuery. Official documentation is often wanting in these areas, and the book fills in the gaps nicely.
Throughout Learning jQuery, additional notation is included to subtly remind developers of any potential gotchas, which is a nice feature. For instance, while referencing the clone() method, it was noted that only elements of the DOM are copied, and not the events previously associated with those elements. These tips are always appreciated, since in a development environment they can prevent hours of head-scratching, and help eliminate frustration.
I was also impressed that the authors cover both JSON and XML as data-interchange formats in Chapter 6, AJAX-How to Make Your Site Buzzword-Compliant. This illustrates conformity not to a single standard, but to real-world development scenarios, where you might encounter both formats. My only complaint here is that not enough time was spent specifically on jQuery's $.ajax() method for AJAX implementations, since in my experience this tends to be more popular than the $.get() method.
The only change I would make to the format of the book would be to divide it into two parts. It is obvious that the authors intended to begin with jQuery key concepts, and then move into cookbook mode. This does happen after Chapter 6, but it would have been helpful to make that distinction more evident. If you do buy the book, be aware that in order to digest these great tutorials, that you should dedicate more time for the latter half of the book.
Finally, I would like to add that although this book does not cover jQuery v.1.2, or the UI plugin, it is still worth the purchase. If you use the latest version of jQuery, and still want to implement the same XPath selectors covered in the book, you just need to download a plugin. You will not find a better resource online for getting into the guts of the jQuery JavaScript library than you will offline reading the book Learning jQuery.

somebody is gonna ask.
jquery This seems like a good place to start.
It's hard to believe that's how Micronians are made. Why don't we see it right now by having you both kiss one another?
While I don't plan to use jQuery, I must commend you on a very well written review. It provides your opinion of the book, without bogging the reader down in chapter-by-chapter recounts of the material.
This site doesn't seem to be updated in a few versions, but it's still very applicable:

As a web developer, I get asked quite a bit about AJAX frameworks/code libraries. I have nothing but praise for jQuery. Here's my take on some of the major players:
1. YUI has been object-oriented to the point of uselessness. Everything requires YAHOO.blah.blah.blah(YAHOO.EventUtil.blah.blah.blah), and then they want you to have another line with YAHOO.AddListener.blah.blah(yourFunction) to add it to the execution list. I like objects. Wait, let me clarify, I like MY objects! I stopped doing what they asked and starting writing wrapper functions to their functions.
2. GWT requires a zillion steps. I spent half a day installing a Java IDE and compiler and running example projects to see how to use it. Perhaps this is useful for massive projects like Gmail, but for the rest of us who are just looking to add a few effects, instead of writing Java to generate JavaScript, you are better off just writing the JavaScript directly.
3. The Scriptaculous documentation seemed nonexistent. I was trying to find meaty documentation, and every page was essentially "LOOK WHAT I CAN DO!1!11"
In short:
1. YUI has a zillion files and still leaves you writing tedious DOM and your HTML ugly. They DO have some good stuff, which I will get to later.
2. GWT is like installing MS Word when you all needed was a good text editor.
3. Scriptaculous will leave you hanging.
(Side Note: I was just learning DOM when I tried out Scriptaculous. The bad taste may be the learning curve all beginner's must go through).
My recommendation:
-Go with jQuery + YUI's "reset-fonts-grids.css" file.
That YUI css file will reset all the browser defaults to an even layout saving you tons cross-browser tweaking. (Some things I disagree with though, like no bullets or numbers on your UL and OL tags. Still worth it though.) YUI Grids also has some nice templates to help you with div-based layouts. They have a few added extras too beyond just JavaScript code libraries.
jQuery is simply the most elegant and concise JavaScript library I've found. The idea behind it, "find this, and then do that", is great. The code looks simple, and your HTML code is left clean! People have developed modules for it too, so I may can replace my YUI added extras and just worry about 1 code library.
Hope that helps someone,
Dan
