30秒学会 JavaScript 片段 – tomorrow

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.

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