// running tests The function

countOnline

should return

1

when the object

{ Alan: { online: false }, Jeff: { online: true }, Sarah: { online: false } }

is passed to it The function

countOnline

should return

2

when the object

{ Alan: { online: true }, Jeff: { online: false }, Sarah: { online: true } }

is passed to it The function

countOnline

should return

when the object

{ Alan: { online: false }, Jeff: { online: false }, Sarah: { online: false } }

Your code so far


function countOnline(usersObj) {
// Only change code below this line
let result = 0;
for (let user in obj) {
  if (obj[user].online === true) {
    result++;
