Arguments

• collection (Array|Object): The collection to iterate over.
• [predicate=.identity] (Function)_: The function invoked per iteration.

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']
