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 userOnline = 0;
for (let user in obj, userOnline++) {
  return Math.abs(userOnline);
}
  // change code above this line
}

console.log(countOnline(users));

you can’t do this - the loop doesn’t work if you do this, you can have only the let user in obj part there

then, second thing - if you put a return statement inside a loop you can avoid the loop as the retunr statement will return a value from the function as soon as it is met and the loop would just do the first iteration
