2. Improvement suggestions:

   • By adding the onUnmounted lifecycle hook, you are correctly cleaning up event listeners. This is good practice and helps prevent memory leaks.
   • Consider organizing your imports more efficiently. You might want to group them based on where they are coming from or their type to make them easier to read and manage.

3. General Comments:

   • The addition of the onUnmounted hook improves the cleanup process, ensuring that event listeners are removed when the component is unmounted, which is a good practice.
   • It's important to maintain consistency in code style and formatting. Ensure that you follow the existing conventions in the codebase to promote readability and maintainability.

Overall, the code changes look appropriate as they address cleanup concerns related to event listeners effectively by incorporating the onUnmounted hook.
