Confsion upon confusion

Tell us what’s happening:

I’m not getting the right result and have no idea where/what detail I’m missing
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(usersObj) {
 // Only change code below this line
let result = 0;
for(let user in countOnline) {
 if (obj[users].online === true) {
}   return result;
 // Only change code above this line

Challenge: Iterate Through the Keys of an Object with a for…in Statement

Link to the challenge:

your function has a parameter with value of an object which you are never using

also you have for user in ...
but then you use the variable users

obj[users] has a double issue: obj is undefined, users is undefined

This is why we needed to see your full code. countOnline is not an object you can iterate through! You need to iterate through your object of users.

Thanx for the input JeremyLT

Thanx for your input JeremyLT

Like JeremyLT said you need to loop over the correct object and not the function.

But just as an aside. Fun fact, a function is an object and can be iterated using for…in. I’m just not sure why you would ever do so.

function countOnline() {
  for (let user in countOnline) {
    console.log(user); // propOnFunction
    console.log(countOnline[user]); // test

countOnline.propOnFunction = 'test';
