Introduction to Objects I 29/33

Try it Out!
This time try making your own function that takes objects as parameters!
Here we have given you the Personconstructor again, along with theageDifference function as an example.
Now create a new function, olderAge. It should take two Person objects as parameters, and return the age of whatever Person is older. For example, with 30 year-old alice and 25 year-old bob, olderAge(alice, bob); should return 30, because that isalice's age and she is older than bob. If the two people have the same age then you can return that age.

Instructions

Define a function called olderAge. We want the function to return the age of the person who is older.

// 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.age > person2.age) {

        return person1.age;

    } else {

        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));
