Compiling to WASM with llvm on macOS
— [howto-wasm-minimal](https://github.com/ern0/howto-wasm-minimal) by Zalka Ernő ([my fork here](https://github.com/simonw/howto-wasm-minimal)) is a neat demo of a minimal WASM module. It uses C++ to define functions for simple image manipulation including blurring an image, compiles it to WASM using llvm/clang++, then uses JavaScript to run those functions against an image loaded into a `<canvas>` element.
