Getting WASM

// es7 async await
(
  async () => {
   
    let importObject;
    const res = await fetch('wasm_test.wasm');
    const bytes = await res.arrayBuffer();
    const results = await WebAssembly.instantiate(bytes, importObject);

    const {add, subtract, loop_add} = results.instance.exports;
  }
)();
