In this lesson, we'll parse the incoming data from Unsplash's API and transform it for our frontend client. Because Cloudflare Workers is serving as "middleware" - in-between the Unsplash API and our frontend client we'll build shortly - we can use it to format or simplify data coming through it that our client doesn't care about. We'll also use the Response class to return a JSON response from our API. JSON responses need to be formatted in a specific way to be able to be parsed by clients, so we'll look at the various pieces of a Response (body and headers) and how they work together to represent a JSON response.
