Review Summary
Your solution is very close, and it correctly implements all the core logic while handling state immutability perfectly. However, one change is needed to better align with the DRY (Don't Repeat Yourself) principle. Inside your switch statement, you create a new state copy ({ ...currentState }) in multiple cases, which is a form of code repetition that goes against a specific requirement [CHECKLIST ITEM #4]. To fix this, please create the state copy just once before the switch block begins, and then have the different cases modify that single copy. This will make your code cleaner and more efficient. After this small change, your solution will be ready for approval!

Review Summary
Great job on the updates! Your code is much cleaner and correctly handles state immutability. This requires one final change to meet all requirements. The switch statement in src/transformStateWithClones.js is missing a default case, which is a specific project requirement for handling unknown action types. [CHECKLIST ITEM #3] Please add a default case to your switch block to complete the task. Once you add that, this will be ready to go!

This implementation is very close! However, the switch statement is missing a default case for handling unknown action types. This violates checklist item #3: 'switch/case should always have default case for error handling'.

Review Summary
Excellent work on this task! You've successfully addressed the previous feedback by adding the default case to the switch statement. Your code is now clean, correct, and fully meets all the requirements. It's great to see you apply the feedback so effectively. Your solution is now complete, fantastic job!
