Numba's JIT compiler now runs in your browser, no Python server required
The Numba JIT compiler now runs entirely in WebAssembly inside JupyterLite, a long-requested feat that required a WASM-aware llvmlite execution engine and in-browser LLVM linking. The demo shows roughly a 250x speedup over standard Python, with gains even larger relative to native. Scientific Python notebooks can now ship as static sites with no server.
