Oh, I never even knew! Oblivious because I have used Windows when using 80 locally, or 8080/3000 when using Linux, or 3000/whatever or something like that in a container. I guess most projects end up working around the problem - and I only use 80 locally when it is the default by whatever set that up - usually Visual Studio (not code). Been a while since I set up a server with nginx and all that. I don't recall having to do anything special, maybe nginx runs privileged. In any case it typically reverse proxies into your app running on a higher port.
