Congrats to @marcoippolito.dev on making it official: type-stripping in Node 25 is now declared to be stable 🎉
You can run: node index.ts
The capabilities have not changed since Node 24. This is purely a maturity indicator.

TS 6.0 is planning a bunch of breaking changes to tsconfig options to deprecate some and change the defaults for others. This will simplify configuration and ease the transition to the Go-based TS 7.0 👍
The latest pitch is to enable strict type-checking modes by default 🎉

It's easy to miss a key feature of Node's TypeScript support that was released on Friday: it's zero config 💥
Meaning you don't need to put anything in package.json. Strictly speaking you don't even need a tsconfig to run the code.

This means Node can run *.ts files. It pairs well with TypeScript's "erasableSyntaxOnly" flag 👍

Type stripping is enabled by default 🔥🔥🔥🔥
You can just run `node file.ts` without `--experimental-strip-types` flag.
This is a huge milestone
