Show HN: You can create promises in JavaScript without nesting

Imagine if you could write:

  const [promise, resolve, reject] = await P();
  // just use resolve() or reject() inline here

Well, now you can! Introducing... one weird trick:

  function P() {
      let p;
      return new Promise(function (resolve) {
          p = new Promise(function (res, rej) {
              resolve([p, res, rej]);
          });
      });
  }
