app.listen(PORT, () => console.log(`Server started on port ${PORT}`));

- Creating routes
- Routes are methods of the `app` object. A get request is `app.get()`.
- Two parameters: the path itself ('/' for home, '/about' for about page) and a function that takes a REQUEST `req` and RESPONSE `res`. The function then has a `res.send()` for whatever you want to display.
- Won't show up bc it needs to be restarted each time.
