- * Returns a new object, where each value corresponds to an array of items, from
- * `coll`, that returned the corresponding key. That is, the keys of the object
- * correspond to the values passed to the `iteratee` callback.
- *
- * Note: Since this function applies the `iteratee` to each item in parallel,
- * there is no guarantee that the `iteratee` functions will complete in order.
- * However, the values for each key in the `result` will be in the same order as
- * the original `coll`. For Objects, the values will roughly be in the order of
- * the original Objects' keys (but this can vary across JavaScript engines).

- * @param {Array|Iterable|Object} coll - A collection to iterate over.
- * @param {AsyncFunction} iteratee - An async function to apply to each item in
- * `coll`.
- * The iteratee should complete with a `key` to group the value under.
- * Invoked with (value, callback).
- * @param {Function} [callback] - A callback which is called when all `iteratee`
- * functions have finished, or an error occurs. Result is an `Object` whoses
- * properties are arrays of values which returned the corresponding key.
- * @example
- *
- * async.groupBy(['userId1', 'userId2', 'userId3'], function(userId, callback) {
- * db.findById(userId, function(err, user) {
- * if (err) return callback(err);
- * return callback(null, user.age);
- * });
- * }, function(err, result) {
- * // result is object containing the userIds grouped by age
- * // e.g. { 30: ['userId1', 'userId3'], 42: ['userId2']};
