What is the use case for linting typescript where tsc is unavailable? To avoid tsc compilation time if possible?

    tsc is (very) slow and there are also no convenient ways to interact with it from Rust.

    So it saves a lot development and CI time to roll our own. The downside is that our inference still isn’t as good as tsc of course, but we’re hopeful the community can help us get very close at least.
