解16进制

// 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");

});
let ast = parse(jscode);
