| * 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'); |
