It really seems that way, but finding good foundations/abstractions is crucial if you are building such megalomaniac project that should cover all JS/TS tooling. It seems they feel pretty good with what they found (Rust & some form of CST) and they will drop formatter soon. We'll see if these foundations will last at least 1000 years.
> But why create a new formatter? When we began our Rust rewrite, we fell in love with rustfmt, Rust’s own formatter. It formatted code instantly, unlike JavaScript formatters which could often take quite a few seconds on larger files.
I write quite a bit of Rust and quite a bit of TypeScript and use both rustfmt and prettier. I really like both tools, but don’t think rustfmt is much faster honestly. I would probably say prettier in VSCode feels a bit more responsive.
