The idea is that booleans only have two values. true and false. If the entered boolean is true it outputs "Yes" if the entere boolean is false it outpits "no" There isnt even any calculation required here. It just directly returns Yes or No depending on whats entered.

I don't think it matters. the logic behind a ternary operator is that if whatever before the "?" is true, then return yes:no, so using (bool === true) ? or bool ? is the same logic.

I did not know about it. thanks :).
