Thank you for your hard work on this task! 😊 While your implementation of the transformStateWithClones function is mostly correct, there are a couple of critical issues that need to be addressed before we can approve the Pull Request:
-
State Cloning Placement: The
stateCloneobject is currently created only once before the loop. To ensure that each action is applied to a fresh copy of the state, the cloning operation should be moved inside the loop, before processing each action. This change is crucial to maintain the integrity of the state for each action and to prevent incorrect results. -
Switch Statement Usage: Although your code processes actions correctly, it uses multiple
ifstatements instead of aswitchstatement. The task requirements specify using aswitchstatement for handling different action types, which helps in organizing the code better when there are a limited number of conditions. -
Default Case in Switch: Since a
switchstatement is not used, there is no default case for error handling. Including a default case is important for handling unexpected action types gracefully.
Once these issues are resolved, your code will be in great shape! Keep up the great work, and don't hesitate to reach out if you have any questions or need further assistance. 🌟

Pushing a copy of the stateClone object to the transformStateResult array should be done after processing each action. Ensure that the state is cloned at the beginning of each loop iteration to maintain the integrity of the state for each action.

Thank you for your submission! 🎉 Your implementation of the transformStateWithClones function shows promise, but there are a few critical areas that need attention to meet the task requirements fully:
-
State Cloning Placement: Currently,
stateCopyis created once before the loop and modified directly, which causes changes to accumulate across actions. To ensure each action is applied to a fresh state, createstateCopyinside the loop before processing each action. -
Switch Statement Usage: While you correctly use a
switchstatement to handle different action types, ensure that the state copy is pushed to the array after processing each action, outside of theswitchblock. This captures the state after all modifications for the current action are complete. -
Default Case in Switch: Consider adding a default case in your
switchstatement to handle unexpected action types gracefully.
These adjustments are crucial for the functionality of your code. Please review the comments and make the necessary changes to improve your solution. This decision is made to help you move forward with your learning journey. Keep up the good work, and use this opportunity to refine your skills! 🚀

The transform function modifies stateCopy, but since stateCopy is not re-created for each action, the changes accumulate across actions. Move the creation of stateCopy inside the loop to fix this.

Similar to the previous comment, the state copy should be pushed to the array after processing the action, outside of the switch block.
