Basic OOP in Js

oop.js

var x = new Object(); // empty object in js
var y= {} ; // another way of creating empty object

// Adding properties to our empty object
y.name="Tim";
y.age=20;
y.getName= function(){
	return this.name;
};

console.log(y);
console.log(y.getName());

// delete operator can be used to remove a property from the object 
delete(y.age);

console.log(y);
// To view the constructor of an object
console.log(y.constructor); 

// Adding private variables
var Pizza = function(){
	var crust='thin'; //private property
  var toppings=3;
  this.hasBacon = true;
  this.getCrust = function(){
  		return crust; // Private variables are available to every object,hence there is no need to use this to access it
  };
  
  // private method
  var getToppings= function(){
  	return toppings;
  };
  var temp = {};
  temp.getToppings= getToppings;
  
  return temp;
};	
var pizzaA = new Pizza();

console.dir(pizzaA); // crust is not visible(private), but hasBacon is visible(public)
console.log(pizzaA.getCrust()); // thin
console.log(pizzaA.getToppings()); // Won't work without returning the temp object. 
// temp works because of Closures!
