"I’m porting the TypeScript Type Checker tsc to Go, and not Rust. As the creator of SWC, an extensible Rust platform, this might sound strange. Let me explain. ... rewriting a massive project such as tsc would be extremely difficult to continue.
tsc: 133.2 seconds (TypeScript)
Rust rewrite: 2.13 seconds(62x faster)
Vercel is sponsoring and funding the work to port tsc to Go. planning to open-source this work in the future.
