// To run this:
// 1. download these files
// 2. run `npm install`
// 3. run `npm run test`
// 4. see if a `data.json` file was written

// https://github.com/node-fetch/node-fetch

// fetch returns a promise so we need it inside an async function

		// possibly don't need json() call here, as we won't be working with the data programmatically but just dumping the string into a file
		const data = await response.json()
		return data

		console.log(`Oh no! ${response.status}: ${error}`)
