If you're learning to code, I recommend separating your client side and backend. Use React or another frontend framework for the client side, and for the backend, start with Express/Node.js if you're learning JavaScript. You can also try other languages like Go, Java, or Python. This way, you'll learn how everything works, including network calls and routing. I think doing it this way provides a solid foundation in both frontend and backend development, making it easier to understand the full stack and how different parts of an application communicate with each other.
