Cloudflare, VoidZero and Owner.com port TypeScript to Rust as tsrs

Why it matters for readers: It shows how rewriting compilers in Rust can speed up tools you use every day and enable new places to run them, like browsers.
- Cloudflare, VoidZero and Max Schwenk are developing tsrs, a Rust port of the TypeScript compiler.1
- Early benchmarks reported that tsrs is up to 8x faster and uses ~70% less memory than TypeScript 7.0 with the same number of type checks.1
- The work is incubated as part of the Oxc JavaScript compiler toolchain and done in close collaboration with the TypeScript team.1
- The teams emphasize they are not forking TypeScript and want the TypeScript team to remain in control of the language’s design and direction.1
- One stated goal is to make TypeScript faster and more memory-efficient so complete development environments can run in more places, including in the browser.1
