Accessing object elements using for loop

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 count =0 ;
  for(let ur in obj){
   return count; 
  // change code above this line

Link to the challenge:


To access the property online inside the objects you need to use obj[ur].online

Because, ur is at first “Alan”, so at first you call obj["Alan"].online, and the same for the others

You use bracket notation because that one can use variables inside it, when dot notation can’t ( would search for something called ur inside the object)
