So I just downloaded the PlayerIO sdk yesterday because I wanted to try doing some online projects (as you do). I was looking through the example code for the Chat room (JavaScript), so that I could do something similar as a starting project, and I found what may perhaps be a bug (maybe).
From what I can see, the code sample deletes a user id from the users array. However, users is not defined, but global.users is defined.
So there are 2 possibilities; Either there is some hidden bit of code which defines the users array and I'm just being dumb, or the devs made an error in the code. Probably the former.
(Sorry if this is in the wrong topic, it's my first time posting and I just thought it was quite peculiar)
EDIT: I ran the sample and indeed, the user doesn't get deleted
