This example displays a full-screen React component that renders the text “It's Anshul singh” in a large, centered font. It uses React 16.13.1 and ReactDOM to mount the `App` component into a `div` with the id `root`. The styling is applied via a CSS class that sets the font size to 13em and centers the text. The data source is a static string of text, and the entire view is produced with a single JSX element.
