Not at all. We are talking about SSR, and the need for a build step (on the backend). That should be pretty obvious considering the explicit mentions of running the code in the browser, jsx, ts, etc. (Not to mention the backend runtime cannot run typescript/jsx without build either)

No it's not. The JIT/interpreter within Deno cannot run this code without doing a build first. This is made very obvious and explicit in the Deno docs.
