|
|
* 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 `isSameISOYear` to `isSameISOWeekYear`.
|
|
* "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} dateLeft - the first date to check
|
|
* @param {Date|Number} dateRight - the second date to check
|
|
* @returns {Boolean} the dates are in the same ISO week-numbering year
|
|
* @throws {TypeError} 2 arguments required
|
|
*
|
|
* @example
|
|
* // Are 29 December 2003 and 2 January 2005 in the same ISO week-numbering year?
|
|
* var result = isSameISOWeekYear(new Date(2003, 11, 29), new Date(2005, 0, 2))
|
|
* //=> true
