After playing with a dozen different JavaScript Libraries such as Prototype, jQuery, YUI, just to name a few, I found every different library has a different way of simulating some sort of Class Hierarchy and provide some sort of Class Inheritance support. (Other than jQuery) Other than being very annoyed that when you create a new class, it has to be library dependent, unless you do the plain old way.
I'm wondering which library offers the best support for class inheritance in general and why.
I hope maybe one day JavaScript Library authors can agree on one style for Class creation and inheritance.

When it comes to inheritance, JavaScript only has one construct: objects. Each object has a private property which holds a link to another object called its prototype. That prototype object has a prototype of its own, and so on until an object is reached with null as its prototype.
Inheritance enables you to define a class that takes all the functionality from a parent class and allows you to add more. Using class inheritance, a class can inherit all the methods and properties of another class. Inheritance is a useful feature that allows code reusability.
The most important difference between class- and prototype-based inheritance is that a class defines a type which can be instantiated at runtime, whereas a prototype is itself an object instance.
I found out there is a Javascript Framework modeled after Ruby:
Js.Class
Another good one is:
Joose-js (modeled after moose (perl) )
I prefer Josse, because it seems to be more actively developed, and the syntax looks neat too!
Any thoughts??? (Maybe this should be another question??)
