Expand on benefits of lifting state up and clarity on game state

Thank you for this fantastic tutorial! I had a couple suggestions, or clarifying questions regarding the following paragraph under Completing the Game > Lifting State Up:

We may think that Board should just ask each Square for the Square's state. Although this approach is possible in React, we discourage it because the code becomes difficult to understand, susceptible to bugs, and hard to refactor. Instead, the best approach is to store the game's state in the parent Board component instead of in each Square. The Board component can tell each Square what to display by passing a prop, just like we did when we passed a number to each Square.

In the second sentence, reasons are listed for lifting the state up, but it'd be incredibly helpful to have examples of these reasons expanded on, even if that expansion is found outside the tutorial. Because this is for beginners, they'll likely not know why these are valid reasons.

Also, in the sentence that begins, "Instead, the best approach..." it seemed confusing to refer to the "game's state" when the seeming antecedent to this is the square's state (first sentence). I would've expected the sentence to read, "Instead, the best approach is to store the Square's state in the parent Board component." Even though the lowercase in "game's" should make it obvious that the author doesn't have the Game component in mind, it still made it hard to discern the intent since the Square's state and the game's state hadn't been equated. Hope that makes sense!

Thank you again for this incredible tool!

Bắt đầu với phần “Completing the Game > Lifting State Up” của tutorial và xem lại đoạn văn được trích dẫn trong issue. Mở rộng phần giải thích về lý do việc đưa state lên cao hơn giúp cải thiện khả năng dễ hiểu, khả năng chống lỗi và refactoring, đồng thời làm rõ state của Square liên quan như thế nào đến state của trò chơi. Được xem là hoàn tất khi cách diễn đạt rõ ràng với người mới bắt đầu và đề cập đến cả hai đề xuất.
