Zig WASM

Open-source Zig projects categorized as WASM

WebAssembly (abbreviated WASM) is a binary instruction format for a stack-​based virtual machine. WebAssembly is an open standard that defines a portable binary-code format for executable programs, and a corresponding textual assembly language, as well as interfaces for facilitating interactions between such programs and their host environment.
