Review Summary
Great job implementing the core logic for this function. You've correctly handled the state transformations and avoided mutation, which is excellent. However, a few changes are needed to fully align with the project's requirements.
Please make the following updates:
- Your
switchstatement is missing adefaultcase to handle unknown action types. This is required for robust error handling. [CHECKLIST ITEM #3] - The variable name
cloneshould be more descriptive. Please rename it to something likestateCopyto follow the naming guidelines. [CHECKLIST ITEM #5] - The JSDoc for the first parameter should be updated from
clonetostateto match the function signature.
Once these adjustments are made, your solution will be ready. Keep up the great work!

The JSDoc here describes a parameter named clone, but the function's first parameter is actually state. Please make sure the documentation accurately matches the function signature.

This violates checklist item #5: 'use proper names for object copy'. The checklist suggests using a more descriptive name like stateCopy instead of clone.

This violates checklist item #3: 'switch/case should always have default case for error handling.'. Your switch statement should include a default case to handle any unknown action types that might be passed in.

Review Summary
You're welcome, and thank you for the updates! You've done a great job improving the variable names and correcting the JSDoc.
This solution requires one final change. The switch statement is still missing a default case, which is required by the checklist to handle unknown action types [CHECKLIST ITEM #3]. As mentioned in the previous review, this is necessary for robust error handling.
Please add a default case to your switch statement. After that, your code will be perfect!
