_.filter(collection, [predicate=_.identity])
Iterates over elements of collection, returning an array of all elements predicate returns truthy for. The predicate is invoked with three arguments: (value, index|key, collection).
Note: Unlike _.remove, this method returns a new array.
Since
0.1.0
Arguments
-
collection(Array|Object): The collection to iterate over. -
[predicate=_.identity](Function): The function invoked per iteration.
Returns
(Array): Returns the new filtered array.
Example
var users = [
{ 'user': 'barney', 'age': 36, 'active': true },
{ 'user': 'fred', 'age': 40, 'active': false }
];
_.filter(users, function(o) { return !o.active; });
// => objects for ['fred']
// The `_.matches` iteratee shorthand.
_.filter(users, { 'age': 36, 'active': true });
// => objects for ['barney']
// The `_.matchesProperty` iteratee shorthand.
_.filter(users, ['active', false]);
// => objects for ['fred']
// The `_.property` iteratee shorthand.
_.filter(users, 'active');
// => objects for ['barney']
