* @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.
|
||||
*
|
||||
* @param {Interval} intervalLeft - the first interval to compare. See [Interval]{@link https://date-fns.org/docs/Interval}
|
||||
* @param {Interval} intervalRight - the second interval to compare. See [Interval]{@link https://date-fns.org/docs/Interval}
|
||||
* @param {Object} [options] - the object with options
|
||||
* @param {Boolean} [options.inclusive=false] - whether the comparison is inclusive or not
|
||||
* @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) },
|
||||
* { start: new Date(2014, 0, 21), end: new Date(2014, 0, 22) }
|
||||
* )
|
||||
* //=> false
|
||||
*
|
||||
* @example
|
||||
* // For adjacent time intervals:
|
||||
* areIntervalsOverlapping(
|
||||
* { start: new Date(2014, 0, 10), end: new Date(2014, 0, 20) },
|
||||
* { start: new Date(2014, 0, 20), end: new Date(2014, 0, 30) }
|
||||
* )
|
||||
* //=> false
|
||||
*
|
||||
* @example
|
||||
* // Using the inclusive option:
|
||||
* areIntervalsOverlapping(
|
||||
* { start: new Date(2014, 0, 10), end: new Date(2014, 0, 20) },
|
||||
* { start: new Date(2014, 0, 20), end: new Date(2014, 0, 24) }
|
||||
* )
|
||||
* //=> false
|
||||
* areIntervalsOverlapping(
|
||||
* { start: new Date(2014, 0, 10), end: new Date(2014, 0, 20) },

* { start: new Date(2014, 0, 20), end: new Date(2014, 0, 24) },
