   * @name max
   * @category Common Helpers
   * @summary Return the latest of the given dates.
   *
   * @description
   * Return the latest of the given dates.
   *
   * ### v2.0.0 breaking changes:
   *
   * - [Changes that are common for the whole library](https://github.com/date-fns/date-fns/blob/master/docs/upgradeGuide.md#Common-Changes).
   *
   * - `max` function now accepts an array of dates rather than spread arguments.
   *
   *   ```javascript
   *   // Before v2.0.0
   *   var date1 = new Date(1989, 6, 10)
   *   var date2 = new Date(1987, 1, 11)
   *   var maxDate = max(date1, date2)
   *
   *   // v2.0.0 onward:
   *   var dates = [new Date(1989, 6, 10), new Date(1987, 1, 11)]
   *   var maxDate = max(dates)
   *   ```
   *
   * @param {Date[]|Number[]} datesArray - the dates to compare
   * @returns {Date} the latest of the dates
   * @throws {TypeError} 1 argument required
   *
   * @example
   * // Which of these dates is the latest?
   * var result = max([
   *   new Date(1989, 6, 10),
   *   new Date(1987, 1, 11),
   *   new Date(1995, 6, 2),
   *   new Date(1990, 0, 1)
   * ])
   * //=> Sun Jul 02 1995 00:00:00
