como usar o tomorrow no javascript es6

Results in a string representation of tomorrow’s date.

Use new Date() to get the current date, increment by one using Date.getDate() and set the value to the result using Date.setDate(). Use Date.prototype.toISOString() to return a string in yyyy-mm-dd format.

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

tomorrow(); // 2018-10-19 (if current date is 2018-10-18)
