Review Summary

Your solution is functionally correct and handles all the state transformations well, which is great! However, this requires a change because the implementation uses if statements to handle the different action types. A specific requirement for this task is to use a switch statement for this kind of conditional logic [CHECKLIST ITEM #2]. Please refactor your code to use a switch on action.type. This change will also make it straightforward to add a default case to handle unknown actions, which is another requirement [CHECKLIST ITEM #3].

This implementation uses multiple if statements to handle the different action types. This violates checklist item #2, which requires using a switch statement. Refactoring to a switch on action.type will also make it easier to add a default case for error handling, as required by checklist item #3.
