Using Dojo to add dynamic capbilities to your web applications can be a little daunting at first.

Let's look at the programming model in more detail to better understand how to use Dojo to build some really cool apps. The programming model is object-oriented inspired and includes "classes" with methods and multi-level inheritance coupled with aspect-oriented event model famous in JavaScript. You will find the API doc quite useful to determine the methods and properties that are inherited from the parent "classes".
