Where I am missing in belowing code ? Can someone help me please ?

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
  for(let obj in users){

  }
  // change code above this line
}

console.log(countOnline(users));

You are using this loop in wrong way.
The obj argument in function countOnline() is object you have to iterate through.
So, you need to use that argument instead of specifically using users object.
It could go something like:

for(everyPerson in obj){
... Check the online status of everyPerson here....
}

See if this helps.
