This fork of "Smiley Face Part II" renders a yellow smiley face that scales to fill the browser window. It uses React and ReactDOM to create an SVG graphic, with the face centered and sized based on the window’s inner width and height. The code draws the head as a circle with a black stroke, plus two eye circles, and omits the mouth shown in the original commented-out SVG markup. The rendering relies on SVG elements and the `window.innerWidth` and `window.innerHeight` properties.
