I think it's interesting how there's two phenomena that seem to be related to me that get posted here and seem to get treated with different responses. One the one hand, we have software originally written in C/C++ being rewritten in Rust (not often, sometimes just conceptualized), and there's often a real push back by some people about how it's a waste and not useful. On the other, we have software rewritten in Java…
It's open source. If you don't like it, don't use it. Rewriting git in Javascript seems pretty useless to me, but who knows, maybe it was a fun challenge for the author.
I suppose that makes sense, kinda...
