## Cloudflare and VoidZero Partner
Cloudflare and VoidZero are now working with Max Schwenk of Owner.com on tsrs, a Rust port of the TypeScript compiler.
## Collaboration with TypeScript Team
We are doing this work in close collaboration with the TypeScript team and incubating tsrs as part of the Oxc JavaScript compiler toolchain.
## Goal of tsrs
Our goal is to help developers spend less time waiting for code checks and more time building.
## Performance Improvements
Early benchmarks show tsrs is up to 8x faster and uses ~70% less memory compared to TypeScript 7.0 with the same number of type check workers.
## Why Not Fork TypeScript
We are not forking TypeScript and believe the TypeScript team should remain in full control of the language’s design and direction.
## Rust Advantages for WebAssembly
Rust’s memory management enables straightforward memory interactions between WebAssembly guest and host, improving memory efficiency for WebAssembly use cases.
## Cloudflare Workers Integration
Cloudflare Workers have supported WebAssembly for a long time and now support native Rust with the new Emscripten target for wasm-bindgen.
## Maintenance Strategy
We are merging tsc-rs and tsrs into a single package with LSP support and content mappers for full TypeScript compatibility.
## Key takeaway

Cloudflare's tsrs, a Rust port of TypeScript, improves speed and memory efficiency for developers.
