/** | |
* 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'); | |
