How WebAssembly Solves a Problem With LLVM

WebAssembly uses LLVM, which is a virtual machine language. WebAssembly by itself doesn't have access to a file system to the network. So if you're loading a WebAssembly binary in a web page, you can provide externally implemented functions. Wazi mimics POSIX style C-scalls for WebAssembly. It's standardized and we do already support Wazi.
