Getting input from the user inside the command line

To start things off, let's run our app from the Terminal. We'll run it pretty similarly to how we ran it in the earlier sections: we'll start with node (I'm not using nodemon since we'll be changing the input), then we'll use app.js, which is the file we want to run, but then we can still type other variables.
