Creating new server in node.js

Firstly install express

const express = require("express")
const app = express()

Then add to server.js or other js files to listen port

app.listen(4000, ()=>{
console.log("server is running on port: 4000")
})

Or if you want to this way. This way is also good. It's best practices

const PORT = process.env.PORT || 4000

app.listen(PORT, ()=>{
console.log(PORT)
})

Put codes in javascript mode like this

const PORT = process.env.PORT || 4000

app.listen(PORT, () => {
    console.log(PORT)
});
