Yes, and clearly typescript is an established tech.

Just look at Cloudflare's wrangler cli.

Everything else is nonsense.

Not really, in the sense that a myriad of alternatives would also meet the same bar,thus its stupid to frame it as "language X can do this, so language X should do it".

The bar is higher than that.

Typescript works well. Cloudflare already has a lot of experience using typescript to develop cli apps that hit their APIs.

Everyone just call down with the bike shedding. You're wasting everyone's time.
