// DarkSky API
// CORS requests are NOT allowed by the DarkSky server
// Requests from other Servers are allowed
// So, we would make a pass thru file on a server.
// Browser sends the fetch( ) AJAX request to OUR server
// OUR server sends the AJAX request to DarkSky server
// DarkSky responds to OUR Server
// OUR Server sends the DarkSky reply back to Browser
// Browser AJAX call => Our Server => DarkSky => Our Server => Browser AJAX call

// To simulate, we will make the call with NodeJS (outside a browser)
// this way, we can avoid the CORS issue.
// It requires installing node-fetch from the terminal
//  npm install node-fetch 
// Then add a require statement at the top of our script
//
let fetch = require('node-fetch');
