I use it from years, it's the only sane way to write typescript.

The learning curve is steep tho.

In any case it's a hard technology to sell, you don't appreciate it from hello worlds. In fact you hate it for trivial programs.

It shows it's benefits at scale.

Lots of tools like T3 and opencode use it at their core because they solve non trivial problems made of queues, retries, dependency injection, schemas, etc.

I've written a vscode extension with it:
