Also, wrapping callback APIs or containing side effects:

  function sleep(ms) {
    return new Promise((resolve) => setTimeout(resolve, ms));
  }
  await sleep(100);

There are some use cases for the Promise class still, and it’s great to have that kind of control facility at hand when you need it.

Promise.withResolvers can fill this gap now (though it's not natively available in Node, yet):

  function sleep(ms) {
    const { promise, resolve } = Promise.withResolvers();
    return setTimeout(resolve, ms), promise;
  }
