Inline NOT operator using boolean

Question

I have this snippet of code:

if (bool) {
    return <code that outputs bool>;
} else {
    return !<same code that outputs bool>;
}

Is there a way to convert the above to something like this so that I don't have to write the code twice?

return (bool? !! : !) <code>;

Answer 1

Found it!

return bool === <code>

I wrote down a truth table and saw this

      code
       T F
      +-+-
     T|T|F
bool  +-+-
     F|F|T

Which is the same table as bool = code
