node核心模块之读取文件

// 基本的读取文件const fs = require("fs");const path = require("path");//异步读取文件console.time('async');fs.readFile(path.join(__dirname,"../world/name.txt"),"utf8",(error,data)=> {//错误优先 if(error) throw error    console.log(data)});console.timeEnd("async");//同步读取文件console.time("sync");var data = fs.readFileSync(path.join(__dirname,"../world/name.txt"),"utf8",(error,data)=> {    if(error) throw error    console.log(data)});console.timeEnd("sync");//---------------------------------打印结果------------------------------------    async: 1.115ms    sync: 0.453ms    console.log("冒险");
