The code doesn’t work, I don’t know the reason, Jeff is there, why does it work in the previous one, but doesn’t work here anymore, there’s confusion again

You are supposed to return a count (a number) from the function.

The function countOnline should return 1 when the object { Alan: { online: false }, Jeff: { online: true }, Sarah: { online: false } } is passed to it
