ExtJS programming - MVC application layout, OOP and more

We are using ExtJS and Zend in the current project.

First we used ExtJS as a supplement for good old HTML - and thinking about programming design was old as well. JavaScript code is expanding and we'll have to reconsider our programming style.

Very good tutorials that we should've started with are:

OOP JavaScript

• JS for OO programmers
• Private variables and methods
• Module Pattern

ExtJS application layout design tutorials

• ExtJS application layout for beginners
• Basic application design
• Extending ExtJS class
