Cars Report
This example displays a text-based car report built with React 16.10. The report filters a hardcoded JSON array of five cars to those priced under $2000, formats each entry with the `formatCar` helper into a string like "2009 Ford F150: $1950", and joins them with newlines into a single message. The message is injected directly into a `<pre>` element via `document.getElementById`, while a separate "Hello React!" message renders into a `<div id="root">` using `ReactDOM.render`. The code uses plain JavaScript array methods (`filter`, `map`, `join`) and React’s classless function components, with no external visualization libraries.
