"JSON is faster"
So I ended up drawing this crude diagram (in the air), successfully arguing that delivering JSON to generate web UIs does in fact merely add complexity and overhead:
server | client | +-- | --> HTML ------------------> DOM | | ^ ----+ | | | | | +-- | --> JSON | | | e.g. React | | parse + - - - - - - - ->+ | | / | | v / | | JS object --templating-> HTML
Might come in handy again sometime…
