Rewrite Bun in Rust has been merged
The Bun project has officially merged a major pull request that rewrites its JavaScript runtime core from Zig to Rust. This significant engineering effort aims to improve performance, maintainability, and attract more contributors from the Rust community. The move positions Bun as an even stronger competitor to Node.js and Deno.
MY TAKE
Rewriting a runtime's core is a monumental task, and Bun's bet on Rust is a huge vote of confidence in the language for high-performance systems. This is a pivotal moment for the JavaScript ecosystem, potentially accelerating a shift towards more memory-safe tooling.
