~~
return a and a or b
~~ →return a or b
correction from @murtaza64
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 b
This doesn't work if a is falsy non-null actually
it’s just
return a and b or c
is the closest Lua has to a ternary operator, but yes, for the above you could shorten it toreturn a or b
(“or
returns the first argument if true, otherwise second argument is returned”)
