JavaScript Express Basics Getting Started with Express Install Express

Cannot GET/ error when trying to execute Express

I'm following the Basic Express tutorial, but at the very beginning, I got stuck. My code is the following one and every time I try to access it through the localhost is says the same "Cannot GET /". I have tried using node.js and my code is running properly yet I cannot make it work with Express.
I have installed the app through npm install and also the plugin for vscode since it is the text editor I'm using. Also I know on the video the port is 3000 but for some reason Express on vscode only allows me to open it on port 80.

const express = require ('express');

const app = express();

app.set('view engine', 'pug' );

app.get('/', (req, res) =>{
    res.render('index');

 });

 app.get('/hello', (req, res) =>{
    res.send('<h1>Hello Javascript developer!</h1>');

 });

app.listen(80, () =>{
    console.log('The application is running on localhost:80');
});  //80 goes to the name of the server
