/**
|

* @name areIntervalsOverlapping
|
||||
* @category Interval Helpers
|
||||
* @summary Is the given time interval overlapping with another time interval?
|
||||
*
|
||||
* @description
|
||||
* Is the given time interval overlapping with another time interval? Adjacent intervals do not count as overlapping.
|
||||
*
|
||||
* ### 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 `areRangesOverlapping` to `areIntervalsOverlapping`.
|
||||
* This change was made to mirror the use of the word "interval" in standard ISO 8601:2004 terminology:
|
||||
*
|
||||
* ```
|
||||
* 2.1.3
|
||||
* time interval
|
||||
* part of the time axis limited by two instants
|
||||
* ```
|
||||
*
|
||||
* Also, this function now accepts an object with `start` and `end` properties
|
||||
* instead of two arguments as an interval.
|
||||
* This function now throws `RangeError` if the start of the interval is after its end
|
||||
* or if any date in the interval is `Invalid Date`.
|
||||
*
|
||||
* ```javascript
|
||||
* // Before v2.0.0
|
||||
*
|
||||
* areRangesOverlapping(
|
||||
* new Date(2014, 0, 10), new Date(2014, 0, 20),
|
||||
* new Date(2014, 0, 17), new Date(2014, 0, 21)
|
||||
* )
|
||||
*
|
||||
* // v2.0.0 onward
|
||||
*
|
||||
* areIntervalsOverlapping(
|
||||
* { start: new Date(2014, 0, 10), end: new Date(2014, 0, 20) },
|
||||
* { start: new Date(2014, 0, 17), end: new Date(2014, 0, 21) }
|
||||
* )
|
||||
* ```
|
||||
*
|
||||
* @param {Interval} intervalLeft - the first interval to compare. See [Interval]{@link docs/types/Interval}
|
||||
* @param {Interval} intervalRight - the second interval to compare. See [Interval]{@link docs/types/Interval}
|
||||
* @returns {Boolean} whether the time intervals are overlapping
|
||||
* @throws {TypeError} 2 arguments required
|
||||
* @throws {RangeError} The start of an interval cannot be after its end
|
||||
* @throws {RangeError} Date in interval cannot be `Invalid Date`
|
||||
*
|
||||
* @example
|
||||
* // For overlapping time intervals:
|
||||
* areIntervalsOverlapping(
|
||||
* { start: new Date(2014, 0, 10), end: new Date(2014, 0, 20) },
|
||||
* { start: new Date(2014, 0, 17), end: new Date(2014, 0, 21) }
|
||||
* )
|
||||
* //=> true
|
||||
*
|
||||
* @example
|
||||
* // For non-overlapping time intervals:
|
||||
* areIntervalsOverlapping(
|
||||
* { start: new Date(2014, 0, 10), end: new Date(2014, 0, 20) },
|
