With two given places it'll tell you which one is further North, South, East or West. Simple.
To get this to run you'll need to get a Google Maps API key. Once you've done that run this
echo '{ "GOOGLE_MAPS": "YOUR-KEY-HERE" }' > api-key.json
This will set up your credential file with your google api key 👍. I'll tidy this when I get round to it.
Then it's just npm i and npm start and you're well away!
