That's ignoring all the negative effects of using typescript.

I was refuting the part about typescript (language and the implementation/language server) being a glorified lint - the value proposition is way higher than that.

Even other dynamic languages started moving in this direction due to the benefits of having type annotations brings to tooling/development experience overall.

The only thing you’ve listed was your preference for readability

True, I did not enumerate them. Adds another step to development and generally adds complexity would be other perceived downsides.

I'll note that most of the upsides are also subjective.

Deno/bun support TS natively, and Node is also adding support.

> adds another step to development

I never understood this. It takes maybe 10 minutes to set up TypeScript in a project if you’ve done it before.

Compared to all the other times involved (time to learn typescript, time saved debugging and writing tests for type errors) the setup time is a total non-issue.
