The Code in html file:
<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>
The Code in JS file:
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);
It is throwing error of Unexpected token '<'?
You need to add the babel to compile it.
Add the following before the before the end of head tag: <script src="includes/Components/React/babel.min.js"></script>
(After the React CDN) and then add the type="text/babel"
to your script so that would be:
<script type="text/babel" src="HelloWorld.js"></script>
I hope you will not see this error.
