Calculates the difference (in seconds) between two dates.
|
|
|
|
- Subtract the two `Date` objects and divide by the number of milliseconds in a second to get the difference (in seconds) between them.
|
|
|
|
```js
|
|
const getSecondsDiffBetweenDates = (dateInitial, dateFinal) =>
|
|
(dateFinal - dateInitial) / 1000;
|
|
```
|
|
|
|
```js
|
|
getSecondsDiffBetweenDates(
|
|
new Date('2020-12-24 00:00:15'),
|
|
new Date('2020-12-24 00:00:17')
|
|
); // 2
|
|
```
