True, with the Angular CLI I believe this has even the default for a while locally but I have yet to encounter incremental compilation during CI e.g.

Also running tests is quite time consuming of you do not run them in parallel.

I guess bazel would be a good fit with Typescript.

As for deno, I did not follow the topic but I hope they at least annotated with JSDoc so developers can get some linting.
