/**
* Computes the symmetric difference between two arrays using a custom mapping function.
* The symmetric difference is the set of elements which are in either of the arrays,
* but not in their intersection, determined by the result of the mapping function.
*
* @template T - Type of elements in the input arrays.
* @template U - Type of the values returned by the mapping function.
*
* @param {...(ArrayLike<T> | null | undefined | PropertyKey | Partial<T> | ((value: T) => unknown))} values - The arrays to inspect, or the function to map array elements to comparison values.
* @returns {T[]} An array containing the elements that are present in either `arr1` or `arr2` but not in both, based on the values returned by the mapping function.
*
* @example
* // Custom mapping function for objects with an 'id' property
* const idMapper = obj => obj.id;
* xorBy([{ id: 1 }, { id: 2 }], [{ id: 2 }, { id: 3 }], idMapper);
* // Returns [{ id: 1 }, { id: 3 }]
