/**
* @name min
* @category Common Helpers
* @summary Returns the earliest of the given dates.
*
* @description
* Returns the earliest 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).
*
* - `min` function now accepts an array of dates rather than spread arguments.
*
* ```javascript
* // Before v2.0.0
* const date1 = new Date(1989, 6, 10)
* const date2 = new Date(1987, 1, 11)
* const minDate = min(date1, date2)
*
* // v2.0.0 onward:
* const dates = [new Date(1989, 6, 10), new Date(1987, 1, 11)]
* const minDate = min(dates)
* ```
*
* @param {Date[]|Number[]} datesArray - the dates to compare
* @returns {Date} - the earliest of the dates
* @throws {TypeError} 1 argument required
*
* @example
* // Which of these dates is the earliest?
* const result = min([
* new Date(1989, 6, 10),
* new Date(1987, 1, 11),
* new Date(1995, 6, 2),
* new Date(1990, 0, 1)
* ])
* //=> Wed Feb 11 1987 00:00:00
