    \section2 Summary of Logical Operators

    You can use the following
    \l{https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Expressions_and_Operators}
    {logical operators} in the expressions to combine several conditions in one
    expression:

    \table
        \header
            \li Operator
            \li Meaning
            \li Evaluates to \c true if
        \row
            \li !
            \li NOT
            \li The condition is not met.
        \row
            \li &&
            \li AND
            \li Both conditions are met.
        \row
            \li ||
            \li OR
            \li Either of the conditions is met.
        \row
            \li <
            \li Less than
            \li The left operand is less than the right operand.
        \row
            \li >
            \li Greater than
            \li The left operand is greater than the right operand.
        \row
            \li >=
            \li Greater than or equal
            \li The left operand is greater than or equal to the right operand.
        \row
            \li <=
            \li Less than or equal
            \li The left operand is less than or equal to the right operand.
        \row
            \li ==
            \li Equal
            \li The operands are equal.
        \row
            \li ===
            \li Strict equal
            \li The operands are equal and of the same type.
        \row
            \li !=
            \li Not equal
            \li The operands are not equal.
        \row
            \li !==
            \li Strict not equal
            \li The operands are of the same type but not equal, or are of
                different type.
    \endtable

    In addition, you can use arithmetic operators to compare numbers before
    checks. However, we recommend that you create separate properties for this
    purpose whenever possible.
