30 * @param {AsyncFunction} iteratee - A function applied to each item in the
31 * array to produce the next step in the reduction.
32 * The `iteratee` should complete with the next state of the reduction.
33 * If the iteratee complete with an error, the reduction is stopped and the
34 * main `callback` is immediately called with the error.
35 * Invoked with (memo, item, callback).
36 * @param {Function} [callback] - A callback which is called after all the
37 * `iteratee` functions have finished. Result is the reduced value. Invoked with
38 * (err, result).
