+ * @name compareDesc
+ * @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.
+ *
+ * @param {Date|Number} dateLeft - the first date to compare
+ * @param {Date|Number} dateRight - the second date to compare
+ * @returns {Number} the result of the comparison
+ * @throws {TypeError} 2 arguments required
+ *
+ * @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
