2. use the `sort` method on the array of objects and pass a custom comparison function as an argument. this function will compare two objects based on a specific key.

3. the custom comparison function should return a negative value if `a` should come before `b`, a positive value if `a` should come after `b`, and zero if the order remains unchanged.

4. after sorting the array of objects, the `students` array will be sorted based on the `age` key in ascending order.

5. you can also sort the objects in descending order by reversing the comparison in the custom function:
