This has also become my biggest issue with Typescript, and a lot of the people I have talked to about it agree this is the biggest pain point. I am not sure what a better system for this would be, but I do hope the Typescript team takes a hard look at this because I could see it being Typescript's Achilles heel.

You don't actually need to do any of this stuff to run typescript. You could use Deno, ts-node, etc. to run code outside of a browser without a separate build step. And there's nothing wrong with using tsc to compile your code to JS for browsers, it's just slower for big projects.

If you have an existing JS project that's being converted to TS, you likely have bundling, linting, and CI handled already; for the most part, you just add `preset: typescript` to your existing Babel config and you're done.

This is an issue with JavaScript that TypeScript inherited. The many module systems and ES versions that need support are insane.
