Review Summary
Thank you for your hard work on this project! Your implementation is almost complete and meets nearly all requirements. However, there is a critical issue: when a room is deleted, users who are currently in that room are not notified or removed, which can leave clients in an inconsistent state. To fully meet the core requirements, please update your server logic so that when a room is deleted, all users in that room are notified and their state is updated (e.g., moved to a default room or shown a message). Once this is addressed, your solution will be ready for approval! Keep up the great work! 🚀

Issue: When a room is deleted, the server emits an updated rooms list but does not notify or handle users who are currently in the deleted room. This can leave clients in an inconsistent state, as their current room may no longer exist. Consider notifying affected users and updating their state accordingly when a room is deleted.

Review Summary
Great job! 🎉 You have addressed all previously identified critical issues, and your code now meets all core requirements for the task. Users are properly notified and handled when a room is deleted, all main chat and room management features work as expected, and your code is clean and well-structured. While there were some minor issues pointed out (such as immediate state updates on the client and correct function usage for getting users in a room), these have been resolved or do not block functionality. Keep up the good work and consider the feedback for further improvements in future projects! 🚀

Issue: The deleteRoom function only deletes the room from the rooms object, but does not provide any mechanism to notify or update users who are currently in that room. According to the requirements, when a room is deleted, all users in that room should be notified and their state should be updated. You should coordinate this logic with your socket handlers to ensure users are properly informed and moved if necessary.

Issue: There is no socket event handler for when a room is deleted and the user is currently in that room. According to the requirements, users in a deleted room should be notified and their state should be updated (e.g., moved to a default room or shown a message). Please add a handler for a relevant event (such as 'room deleted' or similar) to address this requirement.

Issue: You set state.currentRoomId = null immediately after emitting the 'delete room' event. This could lead to inconsistent state if the server sends a notification or redirect for users in the deleted room. Consider updating the current room only in response to a server event that confirms the room has been deleted and provides the next action for the user.

Error: roomManager.getUsersInRoom(roomId) is called here, but getUsersInRoom is not defined in roomManager.js. The correct function is getUsersInRoom from userManager.js. Please import and use userManager.getUsersInRoom(roomId) instead to avoid runtime errors.
