// 将js代码转换成AST
const { parse } = require("@babel/parser");
// 用来遍历AST中的节点
const traverse = require("@babel/traverse").default;
// AST转换成js
const generator = require("@babel/generator").default;
// 用来判断节点类型和生成新的节点
const t = require("@babel/types");
const fs = require("fs");

const jscode = fs.readFileSync("./demo.js", {
    encoding: "utf-8"
});
let ast = parse(jscode);


function delExtra(path) {
    var curNode = path.node;
    delete curNode.extra;
};
traverse(ast, {
    StringLiteral: delExtra,
    NumericLiteral: delExtra
}
);

let code = generator(ast).code;


fs.writeFile('./demoNew.js', code, (err) => { });

 

var _ac = ["\x67\x65\x74\x41\x74\x74\x72\x69\x62\x75\x74\x65", "\x41\x63\x74\x69\x76\x65\x58\x4f\x62\x6a\x65\x63\x74"]

转变成

var _ac = ["getAttribute", "ActiveXObject"]
