//@Desc :使用AST技术，还原code1.js


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/code1.js","utf-8");
let ast =parse(code)

traverse(ast,{
    "UnaryExpression|BinaryExpression|ConditionalExpression|CallExpression":(path) =>{
        const {confident,value} = path.evaluate();
        if(value==Infinity ||value==-Infinity) return;
        confident&&path.replaceWith(types.valueToNode(value));
    },
});

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