Add minutes to date	snippet	javascript	date	lake-trees	2020-11-28T19:27:46+02:00

Calculates the date of n minutes from the given date, returning its string representation.

• Use the Date constructor to create a Date object from the first argument.
• Use Date.prototype.getTime() and Date.prototype.setTime() to add n minutes to the given date.
• Use Date.prototype.toISOString(), String.prototype.split() and String.prototype.replace() to return a string in yyyy-mm-dd HH:MM:SS format.

const addMinutesToDate = (date, n) => {
  const d = new Date(date);
  d.setTime(d.getTime() + n * 60000);
  return d.toISOString().split('.')[0].replace('T',' ');
};

addMinutesToDate('2020-10-19 12:00:00', 10); // '2020-10-19 12:10:00'
addMinutesToDate('2020-10-19', -10); // '2020-10-18 23:50:00'
