WebAssembly is not a programming language; it is a universal, sandboxed virtual machine binary format designed to execute code across any hardware architecture at physical CPU limits.
By banning arbitrary goto jumps and using an abstract evaluation stack, Wasm code is statically verifiable for memory safety in a single linear pass.
64KB memory pages allow high-speed numeric computation and direct byte sharing with JavaScript TypedArrays without data copying.
A WebAssembly module has 0 access to host files, network, or hardware unless explicitly granted capabilities via host import tables.
