Iterate Through the Keys of an Object with a for...in Statement (doesn't work)

Tell us what’s happening:

I don’t understand why isn’t this program running

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 i = 0;
for (let name in obj) {
  if (obj[name].online === true) {
    i =+ 1;
  }
  }
return i;
  // change code above this line
}


console.log(countOnline(users));

I also found someone with a very similar solution that worked…

function countOnline(obj) {
  // change code below this line
  let onlineUsers = 0;
  for(let user in obj){
    if(obj[user].online === true){
      onlineUsers = onlineUsers + 1;
    }
  }
  return onlineUsers;
  // change code above this line
}

You are not using the correct operator here. It should be +=

ohh :laughing: thank you
