Why printErr() of variable that stores zero doesn't do anything?

Feedback & Bugs
#1

Hi there! Im just curious to know why printErr input with ‘zero’ variables doesnt work? Some times it can be useful. Thanks

#2

what language is it?

I bet it’s JS:

printErr(false) // does not work.
                // 0 == false
printErr(0)     // does not work neither.

Q.E.D.
