Why do you say "braindead monkey"?

This is instruction is quite clear:

1) Run the command "node app.js" in your console

2) Open your browser and visit http://localhost:3000

Of course! What else should "run your webserver using [node app.js]" mean?

Yes, Node.js runs completely on the server and *not* in the browser.
Furthermore Node.js applications are designed to run continously while
in PHP a script will only run once for the request then exit again (yes,
PHP-FPM will continue running and waiting for the next request from the
webserver but each PHP script will just be executed again for each
incoming HTTP request).

For example: The script app.js from
<https://nodejs.org/en/docs/guides/getting-started-guide/> will run as
long as you don't stop the "node" process.

The following function will handle all incoming requests from a browser:

const server = http.createServer((req, res) => {
  res.statusCode = 200;
  res.setHeader('Content-Type', 'text/plain');
  res.end('Hello World');
});

"req" is the request object which contains everything sent by the
browser and "res" is the response object which will generate the
response sent back to the browser.
