For what it’s worth I agree with you: after spending years battling with Babel and all that nonsense it’s been amazing to be able to just write ESM JS and have it run both on Node and in the browser. The real lightbulb moment for me was using JSDoc annotations with TypeScript types in JS files. It definitely isn’t as graceful as JS itself but it’s not that big of a deal, plus it encourages you to add comments. And any TypeScript editor will parse the code as if it’s TS, provide autocomplete, type checking etc etc as required.
