Playing around with namespaces, prototype inheritance, and anonymous functions

Here I will throw the code that comes down from the top of my head in my spare time, just to have fun !

script.js

// Namespace "ns" with class (object) extension
var ns = {
  Programmer: function() {
    this.likes = function() {
      console.log("Iron maiden");
    }
  },

  CoolProgrammer: function() {
   var programmer = new ns.Programmer();
   programmer.likes();
  }
};

ns.CoolProgrammer.prototype.doesnotlike = function() { console.log("Rules") };

herve = new ns.CoolProgrammer();
herve.doesnotlike();

// Anonymous function with method rewrite

(function Printer(c, d) {
   c.log = function (str) { d.write("<b>" + str + "</b>") };
   c.log("Splashing ink !");
 }
)(console, document);

//Module parttern (simplest example ever)

var module = (function () {
    //private
    return {
    //public
    }
}());

// Inheriting an object through the prototype property

var Human = function() {

	this.iron = function() {
		return console.log("Iron power !");
	}	

	return this;
};

var Child = function() {

}

Child.prototype = new Human();

var child = new Child();
child.iron();

// Accesing parent instance scope from child instance

var Parent = function() {
  this.name = "Parent";

  this.Child = Child;
  this.Child.prototype.parent = this;
}

var Child = function() {

}

var parent = new Parent();
var child = new parent.Child();

console.log(child.parent.name);

// Inheriting properties

var Status = function(args) {
  var self = this;
  var args = args || {};

  self.setBodyParams = function(args) {
  	self.body = args.body;
  }

  self.setBodyParams(args);

  return self;
};

var Question = function(args) {
  var self = this;
  var args = args || {};

  self.setBodyParams(args);

  return self;
}

Question.prototype = new Status();
Question.prototype.constructor = Question;

var question = new Question({"body": "IAMA BODY"});

console.log(question.body);
