+/**
+ * @name getISOWeekYear
+ * @category ISO Week-Numbering Year Helpers
+ * @summary Get the ISO week-numbering year of the given date.
+ *
+ * @description
+ * Get the ISO week-numbering year of the given date,
+ * which always starts 3 days before the year's first Thursday.
+ *
+ * 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 `getISOYear` to `getISOWeekYear`.
+ *   "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., `getWeekYear`.
+ *
+ * @param {Date|Number} date - the given date
+ * @returns {Number} the ISO week-numbering year
+ * @throws {TypeError} 1 argument required
+ *
+ * @example
+ * // Which ISO-week numbering year is 2 January 2005?
+ * const result = getISOWeekYear(new Date(2005, 0, 2))
+ * //=> 2004
