Share Code on the Front End and Back End?

In your article, you say server code needs to work the same way regardless of whether browser is making a request on its own or some JavaScript based fetch request. Does that not imply, though, that that means node is the only answer? What about people who want to use PHP or Ruby or Blazor or C Sharp or whatever? If you can't share the code on both front end and back end,. Yeah, that's a great question. So think about this architecture as more of taking.
