一段不明所以的JavaScript代码
(function () {
console.log("strart");
const curDate = new Date();
// 获取时间戳
const curTime = parseInt(curDate.valueOf() / 1000);
// 时间戳转换成天数
const curDay = parseInt(curTime / 86400);
console.log(curTime, curTime, curDay);
let n = 21243;
const modRlt = (n + curDay) % 593;
const bolRlt = [13, 37, 73, 137, 313, 433, 577].indexOf(modRlt);
console.log(modRlt, bolRlt);
})();
