Tell us what’s happening:
I can’t seem to figure out the correct methods of properly doing this loop.
Here’s how my mind is processing it:
It needs an if
to determine if online
is true
. I pass the argument plus the iterated user
and the online
key to it using dot notation.
If this equals true it should then push that user into my num
array. Once complete with the loop it can then return the .length
of num
which would be the number of people that were added to the array (online).
Why does this not work though?
Thank you
Your code so far
function countOnline(usersObj) {
// Only change code below this line
let num = [];
for (let user in usersObj) {
if (usersObj.user.online == true) {
num.push(user);
}
}
return num.length;
// Only change code above this line
}
