~~return a and a or b~~ → return a or b

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 to return a or b (“or returns the first argument if true, otherwise second argument is returned”)
