For In statements!

Ok, so I have been struggling with this problem for a few days! I already looked up info on"for in" statements on MDN and I think I am close and I feel like there is some silly mistake I am not even seeing.

function countOnline(obj) {
  // change code below this line

  for (let user in obj) {
    if (obj[user].online === true) {
  return result;
  // change code above this line

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

Link to the challenge:

it doesn’t look like you initialized result

do something like let result = 0 before the for

If you’re a ninja i think there’s a way to init inside the parentheses but I always screw that up.

Got it! It was that plus I used “user” in the function/for in to mirror the example but it really had to be “countOnline”


I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

See this post to find the backtick on your keyboard. The “preformatted text” tool in the editor (</>) will also add backticks around text.

Note: Backticks are not single quotes.
