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

     12  * @static
     13  * @memberOf _
     14  * @since 0.1.0
     15  * @category Collection
     16  * @param {Array|Object} collection The collection to iterate over.
     17  * @param {Function} [predicate=_.identity] The function invoked per iteration.
     18  * @param- {Object} [guard] Enables use as an iteratee for methods like `_.map`.
     19  * @returns {boolean} Returns `true` if any element passes the predicate check,
     20  *  else `false`.
     21  * @example
     22  *
     23  * _.some([null, 0, 'yes', false], Boolean);
     24  * // => true
     25  *
     26  * var users = [
     27  *   { 'user': 'barney', 'active': true },

     31  * // The `_.matches` iteratee shorthand.
     32  * _.some(users, { 'user': 'barney', 'active': false });
     33  * // => false
     34  *
     35  * // The `_.matchesProperty` iteratee shorthand.
     36  * _.some(users, ['active', false]);
     37  * // => true
     38  *
     39  * // The `_.property` iteratee shorthand.
     40  * _.some(users, 'active');
