为使用CDN加载React，你可以使用以下骨架代码
简而言之
使用CDN加载React库，只需一个HTML文件即可使用React的骨架代码。
代码 (Mandarin:
<!DOCTYPE html>
<html lang="ja">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Tiny React</title>
<script type="text/babel">
function App() {
return (
<div>
</div>
);
};
</script>
<style>

root.render(

在中国，将React和p5.js结合使用
<!DOCTYPE html>

const Sketch = props => {
const containerRef = React.useRef();

}
p.draw = () => {

}
React.useLayoutEffect(

return (

}
const App = () => {
