18 | * Returns a new object, where each value corresponds to an array of items, from
|
19 | * `coll`, that returned the corresponding key. That is, the keys of the object
|
20 | * correspond to the values passed to the `iteratee` callback.
|
21 | *
|
22 | * Note: Since this function applies the `iteratee` to each item in parallel,
|
23 | * there is no guarantee that the `iteratee` functions will complete in order.
|
24 | * However, the values for each key in the `result` will be in the same order as
|
25 | * the original `coll`. For Objects, the values will roughly be in the order of
|
26 | * the original Objects' keys (but this can vary across JavaScript engines).

33 | * @param {Array|Iterable|Object} coll - A collection to iterate over.
|
34 | * @param {AsyncFunction} iteratee - An async function to apply to each item in
|
35 | * `coll`.
|
36 | * The iteratee should complete with a `key` to group the value under.
|
37 | * Invoked with (value, callback).
|
38 | * @param {Function} [callback] - A callback which is called when all `iteratee`
|
39 | * functions have finished, or an error occurs. Result is an `Object` whoses
|
40 | * properties are arrays of values which returned the corresponding key.
|
41 | * @example
|
42 | *
|
43 | * async.groupBy(['userId1', 'userId2', 'userId3'], function(userId, callback) {
|
44 | * db.findById(userId, function(err, user) {

45 | * if (err) return callback(err);

46 | * return callback(null, user.age);

47 | * });
|
48 | * }, function(err, result) {

49 | * // result is object containing the userIds grouped by age
|
50 | * // e.g. { 30: ['userId1', 'userId3'], 42: ['userId2']};
