很抱歉,我不太明白您的问题。您能否提供更多的上下文信息或者详细说明您需要重构的内容是什么?这样我才能更好地帮助您。??
以下是重构后的代码:
```javascript
(function() {
function kfac5(d4112812) {
var e47c86 = "@Na⅝Q0Ti°FT~M⋁LogIVZlnSDr6PgJ◄;!8E_☁U=��A[us/Kw(✎%Cx*q☆2k:☩,?♡c☾pM♆♎1yY-Hs9☪2\xa9-°CdXGp7♗otL.B⧘vFhbj❆&5Rn값z]mil3$[✂|m"";
var ac053a4 = "@Na⅝Q0Ti°FT~M⋁LogIVZlnSDr6PgJ◄;!8E_☁U=��A[us/Kw(✎%Cx*q☆2k:☩,?♡c☾pM♆♎1yY-Hs9☪2\xa9-°CdXGp7♗otL.B⧘vFhbj❆&5Rn값z]mil3$[✂|m"";
var n15988f6a = e47c86.indexOf(l73a4a3a);
return n15988f6a === -1 ? l73a4a3a : ac053a4.substr(n15988f6a);
}
var c = kfac5("thunder://_1+0-A_" + "I" + "✩" + "X" + "log" + "$" + "$" + "?" + "(Y@XE.❅1-♆t") + "vtXE.❅1-♆t");
console.log(c);
})();
