WebKit, Google, and Mozilla just released JetStream 3 — the first major overhaul of the benchmark suite since 2019. It drops microbenchmarks in favor of realistic workloads, rewrites WebAssembly scoring, and introduces Dart, Kotlin, and Rust compiled to Wasm.

The pure TypeScript NumPy implementation hits a new performance milestone and adds Float16 support, bringing scientific computing in the browser closer to reality.
