You're missing the point of using TypeScript. How does having native (as in internally having the transpiler embedded) in deno make you suddenly use TS one day? You can use ts-node. How long do you think all the browsers would agree that TS would totally be the future of JS and implement it natively, let alone wait until everyone out there to start using such browsers that non TS supporting browsers are almost all eliminated for them to be ignored? There's a reason TS can be compiled down to ES5. And why are you asking TS for performance over raw JS? Seems off topic from TS' point of view. TS and JS use same principle in the runtime environment and not sure how TS can suddenly beat JS by a good margin. A project that needs multiple minutes for every change sounds like you're doing it wrong. Split the code or use ts-node? And you want to throw away all the benefits of TS until all of the above which I don't really feel are required are solved? I don't see why.
