javascript objects as parameters not returning correct object -


i working on codecademy javascript course, , in 1 have return older age of 2 people. reason returning younger age, cant figure out life of me.

// our person constructor function person (name, age) {     this.name = name;     this.age = age; } // can make function takes persons arguments // 1 computes difference in ages between 2 people var agedifference = function(person1, person2){     return person1.age - person2.age; } // make new function, olderage, return age of // older of 2 people function olderage(){     if(alice > billy){         return alice.age;     }     else{         return billy.age;     } }   // let's bring alice , billy test our new function var alice = new person("alice", 30); var billy = new person("billy", 25);  console.log("the older person " + olderage(alice, billy));

your function compares ages comparing objects not age parameter of object. function:

function olderage() {   if (alice > billy) {     return alice.age;   } else {     return billy.age;   } }

should be:

function olderage(a, b) {   if (a.age > a.age) {     return a.age;   } else {     return b.age;   } }

putting together

i suggest changing code -- fix olderage:

// our person constructor function person (name, age) {     this.name = name;     this.age = age; }  // can make function takes persons arguments // 1 computes difference in ages between 2 people var agedifference = function(person1, person2){     return person1.age - person2.age; }  // make new function, olderage, return age of // older of 2 people function olderage(a, b) {     if (a.age > b.age){         return a.age;     } else {         return b.age;   } }   // let's bring alice , billy test our new function var alice = new person("alice", 30); var billy = new person("billy", 25);  console.log("the older person " + olderage(alice, billy));
