JZ

JZ compiles JavaScript to WebAssembly for audio processing, graphics, simulations, and numerical computing. It infers types and applies SIMD optimizations without requiring type annotations or a rewrite in another language. The compiler is written in JavaScript and runs in Node.js and in the browser, with a CLI, an interactive playground, and runnable examples. JZ is experimental; ongoing work focuses on correctness, predictable memory use, and reliable compilation of real applications.
