21 * in series and therefore the iteratee functions will complete in order.

30 * @param {Array|Iterable|AsyncIterable|Object} coll - A collection to iterate over.
31 * @param {AsyncFunction} iteratee - An async function to apply to each
32 * item in `coll`.
33 * The array index is not passed to the iteratee.
34 * If you need the index, use `eachOfSeries`.
35 * Invoked with (item, callback).
36 * @param {Function} [callback] - A callback which is called when all
37 * `iteratee` functions have finished, or an error occurs. Invoked with (err).
38 * @returns {Promise} a promise, if a callback is omitted
