Examples
In our Fetch Response example (see Fetch Response live)
we create a new Response object using the constructor, passing it a new Blob as a body, and an init object containing a custom status and statusText:
const myBlob = new Blob();
const myOptions = { status: 200, statusText: "SuperSmashingGreat!" };
const myResponse = new Response(myBlob, myOptions);
