In chapter 2, several panels and forms are created by using Ext.extend. I hope you will explain why extend is used and not a simple var panel = new Ext.Panel

Re: Why extend instead of new
my guess is that it is better for object oriented methodology. Basically, it lets you emulate Classes allowing for encapsulation.

But I'm not the author, but it's my guess as it's probably how I'd program it.
