This React starter example demonstrates a simple pet-selection dropdown interface. The app renders a labeled select element populated with animal options (dog, cat, hamster, parrot, spider, goldfish) using React components and props. The code uses React 16.9 and ReactDOM to mount the App component into the page’s root element. The Dropdown functional component maps over an options array to generate the select’s option elements, while the App component composes the label and dropdown together for display.
