Creating classes in Javascript

Hi Guys,

If you searched for classes in javascript ? then you are on the right place, Well like any other technology javascript also supports for oops but unfortunately it does not support for classes, Yes , Javascript is a class-less technology script.

We can simulate class behavior in javascript by creating an object for the function and then we can achieve behavior for accessing various methods of that function through the object created.

Lets take a look 

 
function Car( model ) {
  var value=1; //private member   

  this.model = model;  //all members with this are public
  this.color = "silver";
  this.year  = "2012";
  this.getInfo = function () {
    return this.model + " " + this.year;
  };
}

Now we create an object for this function to access method like this

function Run()
{
var myCar = new Car("ford");
myCar.year = "2010";
alert( myCar.getInfo() );
}

First we create object of Car then we set the year property and then accessed the method , all these are available only because its declared as public with 'this.' but we would not access value member as its declared privately, so here's we are achieving encapsulation by hiding the some members declared privately,which can be used for security purpose.
