9  Logical

9.0.1 Welcome to the Boolean Ballroom: Logical Operators

Are you ready to join the dance of decisions, the waltz of wisdom, the samba of sanity checks? Then, let’s step into the Boolean Ballroom, where Dart’s Logical Operators, the maestros of the Boolean Orchestra, make the magic happen. These operators weave together Boolean values (our darling dancers known as true and false) into a fantastic dance of logic and reason.

Here are our talented choreographers:

  • && The Logical AND Duet: This performance requires both dancers (Boolean values) to be true for the entire dance to be a success. If even one dancer forgets a step (becomes false), the dance is not the same.
bool perfectDuet = (true && true); // True! Both dancers nailed it!
bool stumbledDuet = (true && false); // False! One of the dancers missed a beat. Keep practicing!

|| The Logical OR Ensemble: This is a more forgiving performance. The dance will still shine as long as at least one of our dancers performs flawlessly (is true).

bool amazingEnsemble = (false || true); // True! One dancer’s incredible spin saved the day!

! The Logical NOT Solo: The prima donna of logical operations, it only requires one dancer. This solo performance is a curious one, as the dancer always performs the opposite of what they rehearsed.

bool unexpectedSolo = !true; // False! Wait, we thought they were going to perform a true!

Remember, our Boolean Ballroom depends on perfect timing. So, ensure that you have your conditions and Boolean values in the right order. A misstep in logic can lead to an entirely different dance!

With that, our show in the Boolean Ballroom concludes. Don your top hat, dust off your tailcoat, and ready your Boolean dancers for the next performance in the Dart Disco!
