First, inside our App component, we have a function loadWasm: const loadWasm = async () => { try { setLoading(true); const wasm = await import('hello-wasm'); setWasm(wasm); } finally { setLoading(false); } }; Notably, this function is asynchronous. You might have expected to im...

The first message is pretty direct: you can only use the.awaitsyntax inside anasyncfunction or block. We haven't seen anasyncblock yet, but it's exactly what it sounds like: async {// async noises intensify} The second error message is a result of the first: theasynckeyword causes the...
