Tell us what’s happening:

Your code so far


let users = {
  Alan: {
    age: 27,
    online: false
  },
  Jeff: {
    age: 32,
    online: true
  },
  Sarah: {
    age: 48,
    online: false
  },
  Ryan: {
    age: 19,
    online: true
  }
};

function countOnline(obj) {
  // change code below this line
let count = 0;
for (let user in obj){
count+= user.online;
}
return count;
  // change code above this line
}

console.log(countOnline(users));

You are accessing online property wrong. user.online won’t return anything. Make sure you need to go inside obj first like obj[user]
