Hi Seokjin, Great work on this step as well!
I've added a few comments for improvement.
Try refactoring your code using those suggestions and the two programming requirements below:
- Implement all features using Test-Driven Development (TDD), with unit tests for all logic except UI
- Maintain indentation depth of 1 or less—do not nest more than two levels.
Hope you wrap up this step smoothly and also enjoy your holiday!

You've finally applied the state pattern to this mission! 👍👍
Great to see you reach your goal!

Would it be possible to eliminate this conditional by using polymorphism?

How do you think this conditional could be refactored?

I think it's also possible by using polymorphism like above!

This line reaches through multiple objects, which slightly violates the Law of Demeter.
You might consider exposing a function to encapsulate this access and make the intention clearer!
This is similar to what I mentioned in a previous comment: #833 (comment)

Great job extracting the game result logic into WinningResult! 👍
However, I noticed there's no test coverage for this logic yet.
It would be even better to add tests to make sure this logic is well covered.

Hello Brie, I hope you are doing well.
Came back with third step of blackjack and feel free to add some comments!
Actually, I didn't have much time, so I couldn't give it a lot of thought, and it might be a bit disorganized.
I'm looking forward your feedback.
Thanks and have a nice day 😆
