initialize npm

                                    The npm init command is a step-by-step tool to scaffold out your project. 
It will prompt you for input for a few aspects of the project 
in the following order:

The project's name,
The project's initial version,
The project's description,
The project's entry point (meaning the project's main file),
The project's test command (to trigger testing with something like Standard)
The project's git repository (where the project source can be found)
The project's keywords (basically, tags related to the project)
The project's license (this defaults to ISC - most open-source Node.js projects are MIT)

                                    $ npm init
  ...
  package name: @airnovaet.com/hello-world
  ...
  test command: exit 0
  ...    

                                    //Load HTTP module
const http = require("http");
const hostname = '127.0.0.1';
const port = 3000;

//Create HTTP server and listen on port 3000 for requests
const server = http.createServer((req, res) => {

  //Set the response HTTP header with HTTP status and Content type
  res.statusCode = 200;
  res.setHeader('Content-Type', 'text/plain');
  res.end('Hello World\n');
});

//listen for request on port 3000, and as a callback function have the port listened on logged
server.listen(port, hostname, () => {
  console.log(`Server running at http://${hostname}:${port}/`);
});
