이게 server.js 코드인데

전에 강의와 코드가 겹쳐서 그런거가욤?
겹치면 안되는 코드는 어떤게 있나요 ㅠㅠ

const express = require('express');
const app = express();
const bodyParser = require('body-parser');
app.use(bodyParser.urlencoded({extended : true}));

const MongoClient = require('mongodb').MongoClient;
MongoClient.connect('mongodb+srv://2ckdaks:s3528022@cluster0.0qiowcf.mongodb.net/?retryWrites=true&w=majority', function(에러, client){
app.listen(8080, function(){
console.log('위이이이잉 mongoDB연결 완료')
 })
})

app.listen(8080, function(){
console.log('위이이이잉 서버 가동 ON!!!!');
});

//이거 중요한데 뭐시기 npm 설치안되면 앞에 sudo 붙이자 창민아 한시간 씨름할래?

// 누군가가 /pet 으로 방문을 하면
// pet 관련된 안내문을 띄워주세요

app.get('/pet', function(요청, 응답){
응답.send('펫 쇼핑할 수있 는 페이지임');
});

//hw
app.get('/beauty', function(요청, 응답){
응답.send('뷰티용품 사세요');
})

//이런 쉬봘 ㅈ같은거 디렉터네임 앞에 언더바가 두개임 ㅈㄴ헷갈리누 ㅅㅂ
app.get('/', function(요청, 응답) { 
응답.sendFile(__dirname +'/index.html')
});

app.get('/write', function(요청, 응답) { 
응답.sendFile(__dirname +'/write.html')
 });

//어떤사람이 /add경로로 post요청을 하면...
// ??를 해주세요
app.post('/add', function(요청, 응답){
응답.send('전송완료')
console.log(요청.body.title)
console.log(요청.body.date);
});
