👉 In logic, a conditional statement is a logical expression that takes two values - true or false - and states whether one of those values must be true in order for the other to be true. It can be either "if-then" or "if-else". The truth value of a conditional depends on the values of its operands. For example, if a statement is true, then it cannot be false; conversely, if it's false, then it must be true.
