> But the next advice about not using a different language for frontend and backend is wrong. Being charitable, what I think they are getting at is maybe more about having fully separated frontend and backend applications (since the front-end examples he gives are not languages but frameworks / libraries). Otherwise it seems really backwards - I'm definitely an advocate of not always needing SPA-type libraries, but using literally zero Javascript unless your backend is also JS seems like it goes to a too-far extreme.
