I'm pleased that this year's GitHub survey acknowledges that untyped & typed JavaScript deserve to be counted as part of the same ecosystem.

🔶 Contributor delta (last 12 months): TS +1.1M, Python +0.9M, JS +0.4M

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.

Congrats to @marcoippolito.dev on today's landmark Node 22.18 release. It is the first LTS release to ship unflagged TypeScript support 🎉
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
