This doesn't make sense because you can definitely do live coding in Chrome devtools (which uses V8 of course) and in Nodejs (--watch will reload code changes automatically and there's ways to keep application state through code changes).

Edit - can also apparently do it with TS directly with Deno (also V8), here's an example: https://dev.to/craigmorten/how-to-code-live-browser-refresh-...
