Information Hiding and closures

gistfile1.js

//Information hiding
function User(){
  var username = "Jineesh";
	this.getName = function(){
		return username;
	}
}
var u = new User();
u.getName();


//Closure usage
function getHandler(n) {
    return function() {
        alert( 'You clicked on: ' + n );
    };
}

for (var i = 0; i < 100; ++i) {
    myElements[i].onclick = getHandler(i);
}
