        [Boolean Operators]

        Description

        Logical NOT results in a true if the operand is false and vice versa.

        Example Code

        This operator can be used inside the condition of an if statement.

        if (!x) { // if x is not true  // statements}

        It can be used to invert the boolean value.

        x = !y; // the inverted value of y is stored in x

        Notes and Warnings

        The bitwise not ~ (tilde) looks much different than the boolean not ! (exclamation point or "bang" as the programmers say) but you still have to be sure which one you want where.
