 fetch('./math.wasm').then(response =>
            
            response.arrayBuffer()

        ).then( bytes => WebAssembly.instantiate(bytes) ).then( results => {

            instance = results.instance;

            const add = instance.exports.add;
            
            int result = add(1, 2);

            console.log(" 1 + 2 = " + result );
