Oh boy... I'm still not sure how you deploy a non-PHP webserver to be honest... every language seems to be doing something different, with php you just needed to drag & drop your files in the "public" folder.
The php model is simpler and easy to reason with, but many use cases in modern web development is not possible in this setup and requires you to write your app as a long-running webserver process (e.g. websocket model).
Coming from PHP and having used a bunch of different languages I can understand what you are saying.
Unlike PHP, the other languages run in a process that listens on a port (80, 443 or another). The single process continuously run and handles multiple requests.
Back then, I still had to use NGINX or Apache with PHP, and in retrospect I find that more difficult to understand than a script that listens on a port.
