What would be a good web framework to use as a beginner for my project?

I have being wanting to experiment to recreate the game battleship as a website, I have already made some proyects with JSPs (Jakarta).

At first i thought of using htmx and go because i like the idea of building the interface in the backend, the thing is i'm a little stuck is server-client comunication, for example when the server notifies the client that it is their turn. I saw the concepts of server side events and i don't know if there is another way that i haven't thought.

Thank you for reading this
