What does "=>" do?

const http = require('http');

const hostname = '127.0.0.1';
const port = 1337;

http.createServer((req, res) => {
  res.writeHead(200, { 'Content-Type': 'text/plain' });
  res.end('Hello World\n');
}).listen(port, hostname, () => {
  console.log(`Server running at http://${hostname}:${port}/`);
});

In the Nodejs doc the code to set up the server is different from the example in the video. I changed out the req and res to request and response, see below:

const http = require('http');

const port = 3000;

http.createServer((request, response) => {
  res.writeHead(200, { 'Content-Type': 'text/plain' });
  res.end('Hello World\n');
}).listen(port, () => {
  console.log("Server running at http://<url>/");
});

It's saying that the "() =>" after the port is an unexpected token. What went wrong?
