You passed a second argument to root.render(…) but it only accepts one argument.

react-dom.development.js:86 Warning: You passed a second argument to root.render(…) but it only accepts one argument.

♥ 原因

导入两个组件，需要将两个组件放在一个容器内

const root = ReactDOM.createRoot(document.getElementById('root'))
root.render(<><Header></Header>,<Footer></Footer></>
);
