Calculates the date of `n` minutes from the given date, returning its string representation.
|
|
|
|
- Use `new Date()` 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'
|

```
