Class can extend both custom and built-in classes. Typically custom components would extend built in components (e.g. MyApp.views.ProductsTable would extend built-in Ext.grid.Panel). [10] There is a built-in dynamic loader so classes can have dynamic dependencies (loaded on-demand). There are two types of dependencies in ExtJS.

Prototype also provides library functions to support classes and class-based objects. [2] In JavaScript, object creation is prototype -based instead: an object creating function can have a prototype property, and any object assigned to that property will be used as a prototype for the objects created with that function.
As an example, consider a need of extending the string class with a new reverse method whose return value is a string with the characters in reversed order. Because the string class is a sealed type, the method would typically be added to a new utility class in a manner similar to the following:
Dynamic HTML, or DHTML, is a term which was used by some browser vendors to describe the combination of HTML, style sheets and client-side scripts (JavaScript, VBScript, or any other supported scripts) that enabled the creation of interactive and animated documents.
In Simula, classes are defined in a block in which attributes, methods and class initialization are all defined together; thus all the methods that can be invoked on a class are defined together, and the definition of the class is complete. In Flavors, a mixin is a class from which another class can inherit slot definitions and methods. The ...
