This example presents a minimal HTML page that displays the text “Hello JS” in a preformatted block. It demonstrates how JavaScript updates the DOM by using `document.getElementById` to select the `message-element` and set its `textContent` to the string value from the `message` variable. The page loads `bundle.js` as its only script, with the initial content showing “Hello” before the script runs. The visualization relies on plain browser APIs rather than any external data or rendering library.
