¿Podemos usar JSX, si estamos creando la aplicación vinculando React CDN o mediante biolerplate CRA (create-react-app)?

El código en el archivo html:

 <div id="app"></div> <script src="https://unpkg.com/react@latest/umd/react.development.js" crossorigin></script> <script src="https://unpkg.com/react-dom@latest/umd/react-dom.development.js" crossorigin></script> <script src="HelloWorld.js"></script>

El código en el archivo JS:

 function tick() { const element = ( <div> <h1>Hello, world!</h1> <h2>It is {new Date().toLocaleTimeString()}.</h2> </div> ); return React.createElement('h1', null, 'Hello, ' + element); } setInterval(tick, 1000); const domContainer = document.querySelector('#app'); console.log(domContainer); ReactDOM.render(React.createElement(tick), domContainer);
