This example demonstrates asynchronous data loading in a React application. It displays a loading message while fetching car data, then renders the first car's make model after a simulated two-second delay. The visualization uses React 16.10 and ReactDOM, with data parsed from an JSON string in getCars.js via `JSON.parse`. A React component updates a pre-element through DOM manipulation, showing how to integrate async data fetching with state updates and conditional rendering in a minimal React setup.
