Great job on the Pull Request! 🌟 You've addressed the core functionality well. Just a few minor suggestions: consider using a more efficient approach instead of shift to handle the state history, and try to give more descriptive names to your variables, like renaming newState to stateCopy. These changes can enhance the readability and performance of your code. Keep up the good work! 👍

According to the task description, the initial state object should not be modified. However, adding the initial state directly to the stateHistory array may lead to unintended mutations of the original state object if any modifications are made to the first element of the stateHistory array. Instead, you should add a copy of the initial state to the array.

[NAMING] - The variable newState should have a more descriptive name that indicates it is a copy of the state. Consider renaming it to stateCopy or similar to improve code readability.

The use of shift at line 40 is unnecessary and potentially inefficient since it modifies the original array. Instead, you can initialize stateHistory as an empty array and then push state copies into it as you process actions. This way, you won't need to remove the initial state at the end.
