This example demonstrates how React components pass data through props, rendering a list of jokes where each joke card displays a question and punchline. The `App` component passes a `bunk` object containing optional `question` and `punchline` fields to three `Joke` components. Using inline styles, the `Joke` component conditionally hides the question heading with `display: none` when no question exists, and changes the punchline background to orange for standalone punchlines. The code uses React’s `useState` implicitly through prop passing, with the `ReactDOM.render` API mounting the app.
