Basic Data Structures: Iterate Through the Keys of an Object with a for...in Statement(may 2020)

@JeremyLT already told you exactyl what you did wrong. I have put a lot of arrows on what you SHOULD FOCUS on…

@JeremyLT

             //This is the parameter
                     ↓↓↓↓↓↓↓↓
function countOnline(usersObj) {
  // Only change code below this line
  let result = 0;
//This is not defined... you never declared a variable called obj
                    ↓↓↓
  for (let users in obj) {  
//THE VARIABLE IS NOT DECLARED
        ↓↓↓
    if (obj[users].online === true) {
      result++;
    }
  }
  return result;
  // Only change code above this line
}

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.

Please use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks are not single quotes.

i have but still not been able to through

I am not going to type the code for you. All you need to do is use usersObj instead of obj. I’m not sure how else I can say it.

As I have even put ARROWS on the ones you SHOULD LOOK AT and THINK. We can’t just give you codes, it won’t help you learn. You have to think through it, we helped you enough

thank you. i’v gotten it,

[JeremyLT]

I knew you could figure it out. Good job.

You will want to start your own thread for this rather than hijacking another person’s thread.

We’re going to need more context here to be able to say anything about thing. Where did you see this? How did this show up? What are you trying to do?
