* @category Common Helpers
* @summary Compare the two dates reverse chronologically and return -1, 0 or 1.
*
* @description
* Compare the two dates and return -1 if the first date is after the second,
* 1 if the first date is before the second or 0 if dates are equal.
*
* @typeParam DateType - The `Date` type, the function operates on. Gets inferred from passed arguments. Allows to use extensions like [`UTCDate`](https://github.com/date-fns/utc).
*
* @param dateLeft - The first date to compare
* @param dateRight - The second date to compare
*
* @returns The result of the comparison
*
* @example
* // Compare 11 February 1987 and 10 July 1989 reverse chronologically:
* const result = compareDesc(new Date(1987, 1, 11), new Date(1989, 6, 10))
* //=> 1
*
* @example
* // Sort the array of dates in reverse chronological order:
* const result = [
* new Date(1995, 6, 2),
* new Date(1987, 1, 11),
* new Date(1989, 6, 10)
* ].sort(compareDesc)
* //=> [
* // Sun Jul 02 1995 00:00:00,
* // Mon Jul 10 1989 00:00:00,
* // Wed Feb 11 1987 00:00:00
* // ]
