This example displays a large, centered “Hello Suresh!” message rendered as React text. The app uses React 16.13.1 with ReactDOM to mount a single functional component into the `#root` div. The component returns a `<div>` styled with a 13em font size and center alignment via CSS. The rendering approach relies on React’s `ReactDOM.render` API and JSX, with the message hardcoded in the component. No data source or interactive behavior is present.
