My play play draft implementation of the sleep sort algo. Would nap for a long time for really large numbers though.

sleepsort.js

const unsortedListOfNumbers = [5, 13, 3, 0, 1, 89, 1, 21, 34, 2, 55, 8];
const TIMEOUT_PADDING = 50;

const sleepSort = async listOfNums => {
  const result = [];
  const promises = listOfNums.map(
    num =>
      new Promise(resolve => {
        setTimeout(() => {
          result.push(num);
          resolve();
        }, num * TIMEOUT_PADDING);
      }),
  );

  return Promise.all(promises).then(() => result);
};

const exec = async () => {
  const sorted = await sleepSort(unsortedListOfNumbers);
  console.log(sorted);
}

exec();
