| * 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 | |
