/**

|
|
* Computes the symmetric difference between two arrays using a custom equality function.
|
||
|
|
* The symmetric difference is the set of elements which are in either of the arrays,
|
||
|
|
* but not in their intersection.
|
||
|
|
*
|
||
|
|
* @template T - Type of elements in the input arrays.
|
||
|
|
*
|
||
|
|
* @param {T[]} arr1 - The first array.
|
||
|
|
* @param {T[]} arr2 - The second array.
|
||
|
|
* @param {(item1: T, item2: T) => boolean} areElementsEqual - The custom equality function to compare elements.
|
||
|
|
* @returns {T[]} An array containing the elements that are present in either `arr1` or `arr2` but not in both, based on the custom equality function.
|
||
|
|
*
|
||
|
|
* @example
|
||
|
|
* // Custom equality function for objects with an 'id' property
|
||
|
|
* const areObjectsEqual = (a, b) => a.id === b.id;
|
||
|
|
* xorWith([{ id: 1 }, { id: 2 }], [{ id: 2 }, { id: 3 }], areObjectsEqual);
|
||
|
|
* // Returns [{ id: 1 }, { id: 3 }]
