|
* 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
|
