You can have this now adding types with JSDoc and validating them with typescript without compiling, you get faster builds and code that works everywhere without magic or need to strip anything else than comments.
The biggest pain point of using JSDoc at least for me was the import syntax, this has changed since Typescript 5.5, and it's now not an issue anymore.
