This example displays a static, oversized “hello” text message against a blank page, with the body styled at a font size of 10em. The page is rendered using plain HTML and CSS, with a minimal JavaScript snippet that logs “Hello JavaScript!” to the browser’s developer console. It demonstrates a barebones setup for integrating JavaScript into a web page, using no external libraries or frameworks. The accompanying documentation references a React starter version, but the visible code itself relies solely on native browser APIs for styling and console output.
