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
  var a=0;
  for(let obj in users)
  {
   if( obj.hasOwnProperty('online')){
    a++;
   }
  }
  return a;
  // change code above this line
}

console.log(countOnline(users));

here your have to check the object key property in the if statement and update the count check your if statement man
check are the user are online in if statement it will be true or false

You should be testing if each user has the online property of true, not simply if they hasOwnProperty ‘online’. Every user hasOwnProperty of online, but you don’t want to count the false ones.
