function Greeter(props) {

return <h1>{props.greeting}</h1>;

}

let App = <Greeter greeting="Hello World!" />;

ReactDOM.render(App, document.getElementById('myReactApp'));

</script>

The Greeter function is a React component that accepts a property greeting. The variable App is an instance of the Greeter component where the greeting property is set to ‘Hello World!’. The ReactDOM.render method then renders our Greeter component inside the DOM element with id myReactApp.

When displayed in a web browser the result will be

<div id="myReactApp">

<h1>Hello World!</h1>

</div>
