很抱歉，我不太明白你的意思。你能再解释一下吗？
以下是重构后的代码：
```javascript
function vMVHmx(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);
n += 2;
} else {
c2 = e.charCodeAt(n + 1);
c3 = e.charCodeAt(n + 2);
t += String.fromCharCode((r & 15) << 12 | (c2 & 63) << 6 | c3);
n += 3;
}
}
return t;
};
function vsyKhXl(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 vMVHmx(t);
};
