This is a very specific case, but it can happen: https://github.com/denoland/deno/pull/6793

Ironically deno.

Yeah I think my biggest pain with typescript would be the compile times in larger applications... Although I have very little reference to other compilers with the same code base. I can see why they ditched it

If you take to time to set up incremental compilation, it's really quite fast. For reference, updates to the vscode repo (~5k files) take generally <300ms to recompile, and even incrementally updating after pulling in a batch of hundreds of commits takes only ~10 seconds.

It's concerning to me that the deno folks chose giving up on type safety over figuring out how to set up their development environment to better meet their needs.

in a big application you can throw scala and others into the mix and typescript would still be way slower.
