/**
* Returns the unique elements from n arrays.
*
* This function uses the `setDifference` function to find the elements that are in one array but not in the others.
* It uses the `reduce` method to apply this process to each array in turn, starting with the first two arrays and then using their symmetric difference as the starting point for the next call.
*
* @template T The type of the elements in the arrays. It can be any type.
*
* @param {...T[][]} arrays The arrays to find the unique elements of.
*
* @returns {T[]} An array that contains all elements that are in exactly one of the input arrays.
*
* @example
* const array1 = [1, 2, 3];
* const array2 = [2, 3, 4];
* const array3 = [3, 4, 5];
* const result = uniqueElements(array1, array2, array3); // [1, 5]
