3 * Applies an accumulator function over an iterable sequence from the right, returning the result of the aggregation as a
4 * single element in the result sequence. The seed value, if specified, is used as the initial accumulator value.
5 * For aggregation behavior with incremental intermediate results, scan.
6 *
7 * @export
8 * @template T The type of the elements in the source sequence.
9 * @template R The type of the result of the aggregation.
10 * @param {Iterable<T>} source An iterable sequence to aggregate over.
11 * @param {ReduceOptions<T, R>} options The options which contains a callback and optional seed.
12 * @returns {R} The final accumulator value calculated from the right.
