5 * This method is like `_.sortBy` except that it allows specifying the sort
6 * orders of the iteratees to sort by. If `orders` is unspecified, all values
7 * are sorted in ascending order. Otherwise, specify an order of "desc" for
8 * descending or "asc" for ascending sort order of corresponding values.

11 * @memberOf _
12 * @since 4.0.0
13 * @category Collection
14 * @param {Array|Object} collection The collection to iterate over.
15 * @param {Array[]|Function[]|Object[]|string[]} [iteratees=[_.identity]]
16 * The iteratees to sort by.
17 * @param {string[]} [orders] The sort orders of `iteratees`.
18 * @param- {Object} [guard] Enables use as an iteratee for methods like `_.reduce`.
19 * @returns {Array} Returns the new sorted array.
20 * @example
21 *
22 * var users = [
23 * { 'user': 'fred', 'age': 48 },
24 * { 'user': 'barney', 'age': 34 },
25 * { 'user': 'fred', 'age': 40 },
26 * { 'user': 'barney', 'age': 36 }
27 * ];
28 *
29 * // Sort by `user` in ascending order and by `age` in descending order.
30 * _.orderBy(users, ['user', 'age'], ['asc', 'desc']);
31 * // => objects for [['barney', 36], ['barney', 34], ['fred', 48], ['fred', 40]]
