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

sourcenpm package

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

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

Returns

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

Example

  1. _.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
