Hi campers,
Please help me pass this challenge, The console shows Hello World in glitch but the test doesn’t pass
my code:
myapp.js

const hello = () =>
  console.log("Hello World");
module.exports = hello;

then index.js

// server.js
// where your node app starts

// init project
const express = require('express');
const app = express();
const fcc = require("./myapp");
fcc();

// we've started you off with Express, 
// but feel free to use whatever libs or frameworks you'd like through `package.json`.

// http://expressjs.com/en/starter/static-files.html
app.use(express.static('public'));

// http://expressjs.com/en/starter/basic-routing.html
app.get('/', function(request, response) {
  response.sendFile(__dirname + '/views/index.html');
});

// listen for requests :)
const listener = app.listen(process.env.PORT, function() {
  console.log('Your app is listening on port ' + listener.address().port);
});
