Booleans

The type Boolean represents boolean objects that can have two values: true and false.

Boolean has a nullable counterpart declared as Boolean?.

Built-in operations on booleans include:

• || – disjunction (logical OR)

• && – conjunction (logical AND)

• ! – negation (logical NOT)

The || and && operators work lazily, which means:

• If the first operand is true, the || operator does not evaluate the second operand.

• If the first operand is false, the && operator does not evaluate the second operand.
