Lua. My beloved.

That's valid Python as well
-
It's probably valid javascript that returns "-1" or the empty string depending on if "b" is undefined or null

You don't need the and right? Can't it just be
return a or bThis doesn't work if a is falsy non-null actually
-
it’s just
return a and b or cis the closest Lua has to a ternary operator, but yes, for the above you could shorten it toreturn a or b(“orreturns the first argument if true, otherwise second argument is returned”)
