tomorrow javascript Code Snippet in 2025

Results in a string representation of tomorrow's date.

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

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

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