 * @description
 * Return a date from the array closest to the given date.
 *
 * @param {Date | Number} dateToCompare - the date to compare with
 * @param {Array<Date> | Array<number>} datesArray - the array to search
 * @returns {Date | undefined} the date from the array closest to the given date or undefined if no valid value is given
 * @throws {TypeError} 2 arguments required

 * @example
 * // Which date is closer to 6 September 2015: 1 January 2000 or 1 January 2030?
 * const dateToCompare = new Date(2015, 8, 6)
 * const result = closestTo(dateToCompare, [
