Structuring BlackJack game

Hi everyone 🙂 I created a blackjack game initially with Python and want to embed this now on my webpage and rewrite it in JS. I pretty much have the most functionality like dealing cards, hitting, doubling etc. But I am really struggling with how to put it all together with different game phases. I have several buttons for that and added an eventlistener to them. But those can be pressed at any moment. What I want is to keep the player in the boundries and only let them choose the action in the allowed moment. Do you have any ideas how to accomplish this?
