* @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 unless `inclusive` is set to `true`.
|
|
*
|
|
* @param intervalLeft - The first interval to compare.
|
|
* @param intervalRight - The second interval to compare.
|
|
* @param options - The object with options
|
|
*
|
|
* @returns Whether the time intervals are overlapping
|
|
*
|
|
* @example
|
|
* // For overlapping time intervals:
|
|
* areIntervalsOverlapping(
|
|
* { start: new Date(2014, 0, 10), end: new Date(2014, 0, 20) },
|
|

|
|
* )
|
|
* //=> true
|
|
*
|
|
* @example
|
|
* // For non-overlapping time intervals:
|
|
* areIntervalsOverlapping(
|
|
* { start: new Date(2014, 0, 10), end: new Date(2014, 0, 20) },
|
|

|
|
* )

|
* // Using the inclusive option:
