/**
* @name endOfISOWeekYear
* @category ISO Week-Numbering Year Helpers
* @summary Return the end of an ISO week-numbering year for the given date.
*
* @description
* Return the end of an ISO week-numbering year,
* which always starts 3 days before the year's first Thursday.
* The result will be in the local timezone.
*
* ISO week-numbering year: http://en.wikipedia.org/wiki/ISO_week_date
*
* ### 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).
*
* - The function was renamed from `endOfISOYear` to `endOfISOWeekYear`.
* "ISO week year" is short for [ISO week-numbering year](https://en.wikipedia.org/wiki/ISO_week_date).
* This change makes the name consistent with
* locale-dependent week-numbering year helpers, e.g., `addWeekYears`.
*
* @param {Date|Number} date - the original date
* @returns {Date} the end of an ISO week-numbering year
* @throws {TypeError} 1 argument required
*
* @example
* // The end of an ISO week-numbering year for 2 July 2005:
* const result = endOfISOWeekYear(new Date(2005, 6, 2))
* //=> Sun Jan 01 2006 23:59:59.999
