Create a Separate Array for Sorting:

Declare a new reactive array sortedPostsArray to store the sorted version of posts2. Implement the sorting logic in the button click handlers, directly manipulating sortedPostsArray. The sortedPosts computed property references sortedPostsArray. Modify a Copy of the Array:

Create a copy of posts2 using the spread operator .... Sort the copy and assign it to sortedPostsArray. Key Points:

Avoid Direct Modification: Directly modifying the array within a computed property can lead to unexpected behavior. Create a Separate Array: This ensures the original data remains intact and the computed property updates correctly. Use the Spread Operator: Creates a shallow copy of the array, preventing side effects. Implement Sorting Logic: Customize the sorting logic within the sort method to achieve the desired order. By following these approaches, you can effectively sort the posts2 array and reflect the changes in your Vue component.
