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