function createPerson(){
var o = new Object();
o.sayHello = function(arg){
alert(arg);
}
return o;
}

var person1 = createPerson();
person1.sayHello("hello");

function createPerson(name){
var o = new Object();
o.name = name;
o.sayName = function(){
alert(this.name);
}
return o;
}

var person1 = createPerson("Sprite");
person1.sayName();
