errors with demo

[GravesDXD]

I copy the demo code , but it doesn't run well in React.
react version is the latest.
node version is 17.0.2.
const Jp = () => {
let [id,]=React.useState('')
// Instantiate
React.useEffect(() => {
demo()
}, [id]);

async function demo (params) {
const kuroshiro = new Kuroshiro();
// Initialize
// Here uses async/await, you could also use Promise
await kuroshiro.init(new KuromojiAnalyzer());
// Convert what you want
const result = await kuroshiro.convert("感じ取れたら手を繋ごう、重なるのは人生のライン and レミリア最高！", { to: "hiragana" });
console.log(result)
}
return

123

;
};

export default Jp;
