Sometimes is it worth to rethink the problem. Especially when your condition is based on set-members. Using quantor logic often simplifies the condition :
return
any(x for x in X if x==condition_a)
or all(y for y in Y if y==condition_b)
and all(x for x in X if x==condition_c)
I am not sure if JS has something similar, but this often helps by a lot
Fortunately valve did not use the System Manjaro provides. This would have been a very stupid business decision.
