Prototype Class System

<>p>Dean Edwards came up with Base as a way to give nice inheritence management in JavaScript.

He has tweaked it again.

Iâ€™ve made a couple of tweaks to the class since I last blogged about it. The most important change is that Iâ€™ve renamed the inherit method to base. I caved in to pressure.

These are the other small changes:

added a method to make multiple inheritance (yuk) easier
PLAIN TEXT

JAVASCRIPT:

FlyingFish = Fish.extend();

FlyingFish.implement(Bird);

the Base constructor function can now be used to cast an object to a Base object
PLAIN TEXT

JAVASCRIPT:

var widget = document.getElementById("my-widget");

Base(widget);

widget.extend({

...

});

constructor functions are now inherited (my bad)

Sam Stephenson of Prototype has started blogging and discussed the issues that he has with current inheritence in Prototype, and how Base could become part of Prototype 2.0.

Comment by Dave — May 30, 2006: @Dave – You are mistaken. Base uses prototype based inheritance.
