> I’m from the PHP world of things and need to get experience with what the modern stuff you’re describing. Are there platforms or projects that provide the foundation of what you’re describing? Clojure and ClojureScript is probably the best real-world and actually practical example of this in the wild. .cljc files can be loaded by any Clojure runtime, while .clj files are for Clojure and .cljs are for ClojureScript. Many of the libraries in the ecosystem all use .cljc, so you can use the same libraries both in the backend and in the frontend.
