- * 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).
- *
- * @static
- * @memberOf _
- * @since 0.1.0
- * @category Collection
- * @param {Array|Object} collection The collection to iterate over.
- * @param {Function} [predicate=_.identity] The function invoked per iteration.
- * @param- {Object} [guard] Enables use as an iteratee for methods like `_.map`.
- * @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
