tomorrow

Results in a string representation of tomorrow's date. Use new Date() to get today's date, adding one day using Date.getDate() and Date.setDate(), and converting the Date object to a string.

const tomorrow = (long = false) => {
  let t = new Date();
  t.setDate(t.getDate() + 1);
  const ret = `${t.getFullYear()}-${String(t.getMonth() + 1).padStart(2, '0')}-${String(
    t.getDate()
  ).padStart(2, '0')}`;
  return !long ? ret : `${ret}T00:00:00`;
};

tomorrow(); // 2017-12-27 (if current date is 2017-12-26)
tomorrow(true); // 2017-12-27T00:00:00 (if current date is 2017-12-26)
