This example shows a React application that displays "Home sweet home" as a large text message, along with the string’s character length rendered as HTML. It uses React 16.13.1 and ReactDOM to mount the component into the `#root` element, while independently manipulating the DOM via `getElementById` and `innerHTML` in the initial setup. The styling sets a 13em font size with centered alignment, and the code directly inserts the length message into the page without using React’s virtual DOM for that part.
