WebAssembly support
Deno can execute WebAssembly modules with the same interfaces that browsers provide.
const wasmCode = new Uint8Array([
0, 97, 115, 109, 1, 0, 0, 0, 1, 133, 128, 128, 128, 0, 1, 96, 0, 1, 127,

]);
const wasmModule = new WebAssembly.Module(wasmCode);
const wasmInstance = new WebAssembly.Instance(wasmModule);
const main = wasmInstance.exports.main as CallableFunction
console.log(main().toString());And for files:
const wasmCode = await Deno.readFile("main.wasm");
const wasmModule = new WebAssembly.Module(wasmCode);
const wasmInstance = new WebAssembly.Instance(wasmModule);
const main = wasmInstance.exports.main as CallableFunction;
console.log(main().toString());
