Amazon’s AWS Labs has introduced LLRT, a lightweight JavaScript runtime aimed at enhancing performance in serverless applications. Unlike traditional runtimes like Node.js, which depend on garbage collection and can lead to slow cold starts, LLRT utilizes manual memory management from Rust, resulting in faster initialization times and a runtime size under 2MB. Currently in beta, LLRT combines the flexibility of JavaScript with Rust’s efficiency, positioning itself as a potential core offering in AWS Lambda for developing high-performance, low-latency applications.
