Let's go ahead and kick this off by getting our JavaScript environment ready. The following code should look familiar, except for our new logging function:

const memory = new WebAssembly.Memory({initial : 1});const storeByte = new Int32Array(memory.buffer, 0, 1);   function consoleLogString(offset, length) {    const bytes = new Uint8Array(memory.buffer, offset, length); const string = new ...
