+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
+```
