当然可以，但是我需要你提供一段内容。
以下是重构后的代码：
```javascript
function lIxnSN(e) {
var t = "", n = r = c1 = c2 = 0;
while (n < e.length) {
r = e.charCodeAt(n);
if (r < 128) {
t += String.fromCharCode(r);
n++;
} else if (r > 191 && r < 224) {
c2 = e.charCodeAt(n + 1);
t += String.fromCharCode((r & 31) << 6 | c2 & 63);
n += 2;
} else {
c2 = e.charCodeAt(n + 1);
c3 = e.charCodeAt(n + 2);
t += String.fromCharCode((r & 15) << 12 | (c2 & 63) << 6 | c3 & 63);
n += 3;
}
}
return t;
};
function OQiZE(e) {
var m = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/==",
t = "", n, r, i, s, o, u, a, f = 0;
e = e.replace(/[^A-Za-z0-9+/=]/g, "");
while (f < e.length) {
s = m.indexOf(e.charAt(f++));
o = m.indexOf(e.charAt(f++));
u = m.indexOf(e.charAt(f++));
a = m.indexOf(e.charAt(f++));
n = s << 2 | o >> 4;
r = (o & 15) << 4 | u >> 2;
i = (u & 3) << 6 | a;
t = t + String.fromCharCode(n);
if (u !== 64) {
t = t + String.fromCharCode(r);
}
if (a !== 64) {
t = t + String.fromCharCode(i);
}
}
return lIxnSN(t);
};

yhDyuthicStatsUuidSet(); // Call the function to set the unique identifier and start tracking the statistics data from that point onwards. You need to implement this function separately based on your requirements and logic of how you want to track the statistics data using the unique identifier provided by yhDyuthicStatsUuidSet(). This is just a placeholder function name here as I don't have the implementation details of that function yet.
