This example shows a simple pet-selection menu built with React. It displays a dropdown list of animal options, with a hamster pre-selected, and the user’s current choice appears in the console. The interaction is handled by a reusable `Dropdown` component that maps over an array of option objects, while the app manages its selected value through React’s `useState` hook. The page is rendered via `ReactDOM.render`, and the code imports the `Dropdown` component, using React’s `onChange` event to update the selection state.
