This project really hits WebAsembly’s sweet spot, making use of its ability to port performance intensive C++ algorithms to the web. In this case a real-time image processing algorithm for face detection is compiled to WebAssembly using Emscripten.
Go already has a few different wasm runtime, which allow you to embed and execute wasm modules from within your Go application. However, these are currently interpreters, effectively emulating the WebAssembly Virtual Machine. This post announces a module which embed wasmer within Go - giving a ~100 boost in performance!
