and in the report "22120"

the section code:

function __generator(thisArg, body) {
var f, y, t, g, _ = {
label: 0,
sent: function() {
if (1 & t[0]) throw t[1];
return t[1];
},
trys: [],
ops: []
};
return g = {
next: verb(0),
throw: verb(1),
return: verb(2)
}, "function" == typeof Symbol && (g[Symbol.iterator] = function() {
return this;
}), g;

These codes are auxiliary codes automatically generated by wepack when ES6 is converted to ES, I cannot delete or modify it.

and the section code:

function BIliTools() {}
return BIliTools.av2Bv = function(avNo) {
var av = avNo.toString(), num = NaN;
if ("[object Number]" === Object.prototype.toString.call(av) ? num = avNo : "[object String]" === Object.prototype.toString.call(av) && (num = parseInt(av.replace(/[^0-9]/gu, ""))),
isNaN(num) || num <= 0) return "";
num = (num ^ this.xor) + this.add;
for (var result = __spread("BV1 4 1 7 "), i = 0; i < 6; ) result[this.s[i]] = this.table[Math.floor(num / Math.pow(58, i)) % 58],
i += 1;
return result.join("");
}, BIliTools.bv2Av = function(bv) {
var str = "";
if (12 === bv.length) str = bv; else if (10 === bv.length) str = "BV" + bv; else {
if (9 !== bv.length) return -1;
str = "BV1" + bv;
}
if (!str.match(/[Bb][Vv][fZodR9XQDSUm21yCkr6zBqiveYah8bt4xsWpHnJE7jL5VG3guMTKNPAwcF]{10}/gu)) return -1;
for (var result = 0, i = 0; i < 6; ) result += this.table.indexOf(str[this.s[i]]) * Math.pow(58, i),
i += 1;
return parseInt("av" + (result - this.add ^ this.xor));
}, BIliTools.table = __spread("fZodR9XQDSUm21yCkr6zBqiveYah8bt4xsWpHnJE7jL5VG3guMTKNPAwcF"),
BIliTools.s = [ 11, 10, 3, 8, 4, 6 ], BIliTools.xor = 177451812, BIliTools.add = 8728348608,
BIliTools;

These codes are the conversion functions of the AV number and BV number of the bilibili website, just like the function name
