_.some

_.some(collection, [predicate=_.identity])

Checks if predicate returns truthy for any element of collection. Iteration is stopped once predicate returns truthy. The predicate is invoked with three arguments: (value, index|key, collection).

Since

0.1.0

Arguments

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

Returns

(boolean): Returns true if any element passes the predicate check, else false.

Example

_.some([null, 0, 'yes', false], Boolean);
// => true
 

var users = [
  { 'user': 'barney', 'active': true },

  { 'user': 'fred',   'active': false }
];
 
// The `_.matches` iteratee shorthand.
_.some(users, { 'user': 'barney', 'active': false });
// => false
 
// The `_.matchesProperty` iteratee shorthand.
_.some(users, ['active', false]);
// => true
 
// The `_.property` iteratee shorthand.
_.some(users, 'active');
// => true
