Basic Data Structures: Iterate Through the Keys of an Object with a for...in Statement question

[JeremyLT]

@sp2012

for (let online in usersObj[user]) {

Can you describe what you want this line to do please?

@sp2012

for (let online in usersObj[user]) {

JeremyLT, to loop through the online keys of user.

Ah, but a single user only has a single online key. You don’t need a loop here because you are already looping over each user. You need to check the single online key for the current user.

Was my explanation ok, or is there a part I can improve?

Thank you for your reply, it helped me solve the challenge.

I am glad I was able to help. Good work figuring it out!
