Function some

  • 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).

    Type Parameters

    • T


    • collection: ArrayLike<T>

      The collection to iterate over.

    • Optionalpredicate: any

      The function invoked per iteration.

    • Optionalguard: any

      Enables use as an iteratee for methods like map.

    Returns boolean

    Returns true if any element passes the predicate check, else false.


    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
