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

|
* @category Collection |
|
* @param {Array|Object} collection The collection to iterate over. |
|
* @param {Function} [predicate=_.identity] The function invoked per iteration. |
|
* @returns {Array} Returns the array of grouped elements. |
|
* @example |
|
* |
|
* var users = [ |
|
* { 'user': 'barney', 'age': 36, 'active': false }, |
|
* { 'user': 'fred', 'age': 40, 'active': true }, |
|
* { 'user': 'pebbles', 'age': 1, 'active': false } |
|
* ]; |
|
* |
|
* _.partition(users, function(o) { return o.active; }); |
|
* // => objects for [['fred'], ['barney', 'pebbles']] |
|
* |
|
* // The `_.matches` iteratee shorthand. |
|
* _.partition(users, { 'age': 1, 'active': false }); |
|
* // => objects for [['pebbles'], ['barney', 'fred']] |
|
* |
|
* // The `_.matchesProperty` iteratee shorthand. |
|
* _.partition(users, ['active', false]); |
|
* // => objects for [['barney', 'pebbles'], ['fred']] |
