C++ Everywhere with WebAssembly
summary
Shows that you can bind C++17 to HTML5 and run the same ABI on browser and server by compiling to WebAssembly with Emscripten and the nxxm toolchain, including a demo framework named Bellevue and a build command called xm that compiles C++ embedded in HTML. Claims portable native performance with the same module on Node.js and browsers, notes pthreads depend on SharedArrayBuffer (disabled in many browsers), and reports JS callbacks about two times faster but C++ twice as stable under heavy GC in live benchmarks.
