import {traverse, types} from "@babel/core";
import {parse} from "@babel/parser";
import CodeGenerator from "@babel/generator";
// import * as types from "@babel/types";
import fs from "fs";


const code = fs.readFileSync("code/code2.js", "utf-8");
let ast = parse(code)

traverse(ast, {
    "StringLiteral"({node}) {
        //这个正则表达式用于匹配字符串中是否包含\u或\x的转义序列，这两个序列分别用于Unicode和十六进制的字符转义,g表示全局,i表示不区分大小写
        if (node.extra && /\\[ux]/gi.test(node.extra.raw)) {
            node.extra.raw = node.extra.rawValue;

const {code: output} = CodeGenerator.default(ast);
console.log(output)
