Using object() method
Based on the idea that objects inherit from objects, Douglas Crockford advocates the use of an object() function that accepts an object and returns a new one that has the parent as a prototype:
function object(o) {
function F() {}
F.prototype = o;
return new F();
}
If you need access to an uber property, you can modify the object() function as follows:
function object(o) {
var n;
function F() {}
F.prototype = o;
n = new F();
n.uber = o;
return n;
}
Using this function is the same as using extendCopy(), you take an object such as twoDee, create a new object from it, and then proceed to augmenting the new object:
var triangle = object(twoDee);
triangle.name = 'Triangle';
triangle.getArea = function () {
return this.side * this.height / 2;
};
The new triangle still behaves the same way:
>triangle...
