 * @param {Array|Iterable|Object} coll - A collection to iterate over.
 * @param {Function} iteratee - A function to apply to each
 * item in `coll`. The iteratee is passed a `callback(err)` which must be called
 * once it has completed. If no error has occurred, the `callback` should be run
 * without arguments or with an explicit `null` argument. The array index is
 * not passed to the iteratee. Invoked with (item, callback). If you need the
 * index, use `eachOfSeries`.
 * @param {Function} [callback] - A callback which is called when all
 * `iteratee` functions have finished, or an error occurs. Invoked with (err).
