Operator Description a === b a equal to b, including x and z (Case equality) a !== b a not equal to b, including x and z (Case inequality) a == b a equal to b, result may be unknown (logical equality) a != b a not equal to b, result may be unknown (logical ...
You may use case-equality operator (===) or case-inequality operator (!==) to match including X and Z and will always have a known value. OperatorDescription a === b a equal to b, including x and z a !== b a not equal to b, including x and z a == b a equal to b, ...

*单目运算符(unary operator):可以带一个操作数,操作数放在运算符的右边。 *二目运算符(binary operator):可以带二个操作数,操作数放在运算符的两边。 *三目运算符(ternary operator):可以带三个操作,这三个操作数用三目运算符分隔开。 见下例:
