How to use object oriented server side javascript

function myClass(param1, param2) {

   var private_member1 = param1;

   var private_member2 = param2;

  this.method1 = function () {

    // do something

  }

  this.method2 = function(param1, param2) {

    // do something

   // you can access method1 and private member variables directly 

  }

}

var object1 = new myClass("one", "two");

object1.method1();

object1.method2("another param1", "another param2");

var object2 = new myClass("three", "four");

// and so on

var myClass2 = new function() {

  this.method1 = function(param) {

    return "this is an example";

  }

  // and so on, just like the example above

}

alert(myClass2.method1());

function rootObject() {

  this.log(msg) {

   print(msg);

  }

}

function subObject() {

  this.inheritFrom = rootObject();

  this.inheritFrom();

}

var o = new subObject();

o.log("test");
