Create an HTTP Server

Open the editor on the right. You should see a file named app.js in your editor.

Requirements

Create a server by writing code in app.js that runs on port 8080.
The server should respond with "hello world" to all incoming requests.
Start the server by running node app.js in the terminal.

Example

After completing the task, the service should be running on port 8080. Open "Web 8080" at the top of the VM and refresh it manually. You should see "hello world" displayed on the screen.

Summary

This challenge involves creating a basic HTTP server using Node.js. The server listens on port 8080 and responds with "hello world" to any incoming request.

To complete this task, you need to:

Import the http module.
Use the createServer method to instantiate the server.
Define a callback function that sends "hello world" as the response.
Use the listen method to make the server listen on port 8080.

This challenge demonstrates fundamental concepts of creating an HTTP server with Node.js, including request handling and response generation in web development.
