Programs written to run on conventional operating systems typically depend on OS abstractions like processes, pipes, signals, sockets, and a shared file system. Compiling programs into JavaScript, asm.js, or WebAssembly with tools like Emscripten or GopherJS isn’t enough to successfully run many programs client-side, as browsers present a non-traditional runtime environment that lacks OS functionality. Porting these applications to the web currently requires extensive rewriting or paying to host significant portions of code in the cloud.
