/**

 * 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
