What will be the results of the following alerts, given the code snippet below?

function newClass() {
this.firstName = "Kheme";
lastName = "in Cyprus";
}
var nc = new newClass();
alert(nc.firstName);
alert(nc.lastName);

2 pop up
first 1 says kpeme
second says undefined because the lastname variable you defined in the class has no "this"

so you can't access the variable except from within the class definition

function newClass() {
   this.firstName = "Kheme";
   lastName = "in Cyprus";
   this.seun=lastName; //we are accessing the lastName variable from here
}   
var nc = new newClass();
alert(nc.firstName);
alert(nc.seun);

Brilliant!

need i say anything?
