    [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.
