29/33....anybody help


// Our person constructor
function Person (name, age) {
this.name = name;
this.age = age;

// We can make a function which takes persons as arguments
// This one computes the difference in ages between two people
var ageDifference = function(person1, person2) {
return person1.age - person2.age;

// Make a new function, olderAge, to return the age of
// the older of two people
var olderAge = function(person1,person2){
if(person1 > person2){
return person1.age;
return person2.age;


// Let's bring back alice and billy to test our new function
var alice = new Person("Alice", 30);
var billy = new Person("Billy", 25);

console.log("The older person is " + olderAge(alice, billy));


How do you know if person1 is greater than person2? Like, person1 and person2 don't have a number?!

The problem is that in your "if" statement, you are supposed to put person1.age and person2.age instead of person1 and person2.

Hope it helped!:smiley:
