To create a web server using Node.js, you can follow these steps:

  • Install Node.js on your computer.
  • Open a command prompt and run the "npm init" command. This will generate the package.json file for your project.
  • Install the Express.js library by running the command "npm install express".
  • Copy the following code into a JavaScript file and run the file:
const express = require('express')
const app = express()
const port = 3000

app.get('/', (req, res) => res.send('Hello World!'))

app.listen(port, () => console.log(`Example app listening on port ${port}!`))

This code creates a web server and when you go to "http://localhost:3000" in your browser, "Hello World!" displays the text.
