+/**
+ * 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 _
+ * @category Collection
+ * @param {Array|Object} collection The collection to iterate over.
+ * @param {Function|Object|string} [predicate=_.identity] The function invoked per iteration.
+ * @param- {Object} [guard] Enables use as an iteratee for functions 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 }
+ * ];
+ *
+ * // using the `_.matches` iteratee shorthand
+ * _.some(users, { 'user': 'barney', 'active': false });
+ * // => false
+ *
+ * // using the `_.matchesProperty` iteratee shorthand
+ * _.some(users, ['active', false]);
+ * // => true
+ *
+ * // using the `_.property` iteratee shorthand
+ * _.some(users, 'active');
