This example demonstrates a simple interactive button that triggers a JavaScript function when clicked. The page displays a large “Click me” button centered on a white background, and clicking it logs “Hello JavaScript!” to the browser’s console. The implementation uses plain HTML and CSS for layout and styling, with the click handler defined in `index.js` and loaded via a bundled script. React is listed as the framework, though the visible code relies directly on native DOM event handling rather than React components.
