/**
* Sorts an array of objects based on multiple properties and their corresponding order directions.
*
* This function takes an array of objects, an array of criteria to sort by, and an array of order directions.
* It returns the sorted array, ordering by each key according to its corresponding direction ('asc' for ascending or 'desc' for descending).
* If values for a key are equal, it moves to the next key to determine the order.
*
* @template T - The type of elements in the array.
* @param collection - The array of objects to be sorted.
* @param criteria - An array of criteria (property names or property paths or custom key functions) to sort by.
* @param orders - An array of order directions ('asc' for ascending or 'desc' for descending).
* @param [guard] Enables use as an iteratee for methods like `_.reduce`.
* @returns The sorted array.
*
* @example
* // Sort an array of objects by 'user' in ascending order and 'age' in descending order.
* const users = [
*   { user: 'fred', age: 48 },
*   { user: 'barney', age: 34 },
*   { user: 'fred', age: 40 },
*   { user: 'barney', age: 36 },
* ];
* const result = orderBy(users, ['user', (item) => item.age], ['asc', 'desc']);
* // result will be:
* // [
* //   { user: 'barney', age: 36 },
* //   { user: 'barney', age: 34 },
* //   { user: 'fred', age: 48 },
* //   { user: 'fred', age: 40 },
* // ]
