Function extender for JavaScript

extends.js

Function.prototype.method = function(name, func) {
	this.prototype[name] = func;
	return this;
}

Function.prototype.extends = function(superclass) {
	this.prototype = Object.create(superclass.prototype);
	this.prototype.constructor = this;
}

/* Example:
	function Animal(){};
	function Bird(){};
	function Bird.extends(Animal);
	function AddFlight(o) = {
		o.fly = function (){console.log("Flying");};
		o.land = function (){console.log("Landing");}
	}
	addFlight(Bird.prototype); 
	Bar.prototype = Object.create(Foo.prototype);
        Bar.prototype.constructor = Bar; // <-- add this line!
