JavaScript Create a Reusable Fetch Function

Other ways to make fetch modular and easier to maintain?

He says in the video you can find more info in the teacher's notes, but I don't see anything. Anyone have a link I can use to view better ways to use fetch aside from the fetchData function in the tutorial?

Perhaps this doesn't answer your question, but you may like this pattern:

async function doSomething {
  const data = await (await fetch(url)).json();
  // deal with data
};

The outer call (await (expression).json()) waits for the inner call (await fetch(url)) to resolve before firing, and may save you having to write a fetch function requiring maintenance in the first place. This pattern can be found in this FreeCodeCamp tutorial (rest of the tutorial irrelevant for this particular issue).
