4 * Creates an array of elements split into two groups, the first of which
5 * contains elements `predicate` returns truthy for, the second of which
6 * contains elements `predicate` returns falsey for. The predicate is
7 * invoked with one argument: (value).
8 *

10 * @memberOf _
11 * @since 3.0.0
12 * @category Collection
13 * @param {Array|Object} collection The collection to iterate over.
14 * @param {Function} [predicate=_.identity] The function invoked per iteration.
15 * @returns {Array} Returns the array of grouped elements.
16 * @example
17 *
18 * var users = [
19 * { 'user': 'barney', 'age': 36, 'active': false },
20 * { 'user': 'fred', 'age': 40, 'active': true },
21 * { 'user': 'pebbles', 'age': 1, 'active': false }
22 * ];
23 *
24 * _.partition(users, function(o) { return o.active; });
25 * // => objects for [['fred'], ['barney', 'pebbles']]
26 *
27 * // The `_.matches` iteratee shorthand.
28 * _.partition(users, { 'age': 1, 'active': false });
29 * // => objects for [['pebbles'], ['barney', 'fred']]
30 *
31 * // The `_.matchesProperty` iteratee shorthand.
32 * _.partition(users, ['active', false]);
33 * // => objects for [['barney', 'pebbles'], ['fred']]
34 *
35 * // The `_.property` iteratee shorthand.
36 * _.partition(users, 'active');
37 * // => objects for [['fred'], ['barney', 'pebbles']]
