This example demonstrates a minimal React application that renders an "Hello JSX" heading onto a web page. The code uses React 17 and ReactDOM to mount a functional component into a root div, with the page styled to remove margins and hide overflow. A commented-out SVG block shows a yellow circle with eyes, but the active rendering only displays the text heading. The project imports React directly via UMD scripts and runs from a bundled JavaScript file.
