The folks at Packt asked me to review another of their book on Learning EXTJS 4 If you are interested in buying it (a judgment you may reserve until after you have read the review)EXTJS4 is on packt site
this is link you can go.Learning EXtJs 4 is on packt site

Crysfel Villa ,Armando Gonzalez are author of this book.Crysfel Villa is a Software Engineer with more than 7 years of experience with JavaScript on a daily basis.Armando Gonzalez is a Software Engineer with more than 4 years of experience
in developing enterprise applications with Ext JS. He has plenty of experience in
server-side technologies like PHP, Java J2EE, Node JS, and ROR.

The first thing you will probably notice is the size of the document. This is no brief summary of the new features. This is small book of over 40 pages covering to learn a new java script librart with a full index in the back. The structure of the book is:
Business overview

Step 1 – The Basics
Step 2 – The Core Concepts
Step 3 – Components and Layouts
Step 4 – It’s All About the Data
Step 5 – Buttons and Toolbars
Step 6 – Doing it with Forms
Step 7 –Give me the Grid
Step 8 – Architecture
Step 9 – DataViews and Templates
Step 10- The Tree Panel
Step 11 – Drag and Drop
Step 12 – Look and Feel
Step 13- From Drawing to Charting

I like this structure as it parallels the steps one would take in setting up a EXTJS 4. To add a bit of a flow to the book, they also put it in the examples,real life scenarios.

Its more a starter book.This book focuses on giving the reader a firm understanding of the core concepts of EXTJS, such as Drag and Drop and tree panel, and works through real-life app development scenarios. All core components of EXTJS’s amazing library are covered in detail, and strategies are outlined for getting the best use of time when developing with EXTJS.

Few components which i like to mention , which i enjoy reading alot – a clear explanation of how to make drag drop using EXTJS.
How tree panel compoenent work.How you can make charts components for example pie,bar , gauage. Skinning of application is well defined.

Ext JS is a JavaScript library for building interactive web applications using techniques such as Ajax, DHTML, and DOM scripting.

Ext JS 4 features expanded functionality, plugin-free charting, and a new MVC architecture, it’s the best Ext JS web application development platform yet. It helps develop incredible web apps for every browser.
