tomorrow

Results in a string representation of tomorrow's date.

First we use new Date() to get today's date, then add one day using Date.getDate() and mutate the initial Date via Date.setDate(). The we use .toISOString to get the date part of the string – discarding the time part.

const tomorrow = () => {
  let t = new Date();
  t.setDate(t.getDate() + 1);
  return t.toISOString().split('T')[0];
};

tomorrow(); // 2018-10-18 (if current date is 2018-10-18)
// if you need the time to indicate the start of the day as well:
`${tomorrow()}T00:00:00}: // 2018-10-18T00:00:00
