fetch(URL)
// Call to the fetch function to grab data from the given API
// This returns a promise
.then(response => response.json( ))
// Once the promise is fulfilled, it returns a response object which exposes a json method.

.then(function(resp))
// This json method returns yet another promise which can then be chained on to another
// .then(), which at that point can be logged to the console, or passed as an argument to another function.
