Nice demo! Note that strings are already iterable, so you can simplify spell like this:

async function* spell({ sentence, slowness = 75 }) {
  for (const char of sentence) {
    await delay(slowness);
    yield char;
  }
}

True! It actually implements Symbol.iterator. thanks for pointing it out. :)
