Promise._sleep(ms)

[coolaj86]

• Promise._sleep(n)
• Proimse._map(arr, fn)
• Proimse._parallel(n, arr, fn)

Another one of those things that just ought to be included.

As simple as it is, it's darn useful for:

• Tests
• CLI output
• Rate-limiting

/**
 * @param {Number} ms
 * @returns {Promise<void>}
 */
Promise._sleep = async function (ms) {
  return await new Promise(function (resolve) {
    setTimeout(resolve, ms);
  });
};
