This is the status update for stc (opens in a new tab), the new TypeScript type checker written in Rust.

TL;DR;

Stats:

Stats {
    Matched: 5891 => 5881,
    Bad (required): 4183 => 4193,
    Bad (excess): 825 => 714,
    Bad (panic): 18,
}

This is the diff for the commit used for previous status update (opens in a new tab) and the last commit on 2/5 (opens in a new tab). I took vacation this week, so there was a lot of progress.

Contributions

There was one contributor this week, but he's a long-term contributor and he contributed a lot of code. Thank you!

Noticable changes

Change of the testing strategy

I'm working to split the official conformance test suite from tsc into smaller unit tests. Once it's finished, progress will be much faster.
