You need to pay attention to the remainder operation of special operands:

var n = 5;  //定义并初始化任意一个数值
console.log(Infinity % n);  //返回NaN
console.log(Infinity % Infinity);  //返回NaN
console.log(n % Infinity);  //返回5
console.log(0 % n);  //返回0
console.log(0 % Infinity);  //返回0
console.log(n % 0);  //返回NaN
console.log(Infinity % 0);  //返回NaN
