JavaScript

Lets suppose I made a class called Person. var Person = function(fname){this.fname = fname;};

pObj is the object I made from this class. var pObj = new Person('top');

now I add one property to Person class, say lname. Person.prototype.lname = "Thomsom";

now pObj.lname gets me "Thomson".

My question is that, when pObj didn't find the property lname in it, how does it know where to look for.
