Rendering performance is mainly a function of how much you render - too much DOM will slow your site to a crawl. Native platforms actually have the same problem, but they stay fast by promoting virtual scrolling: rendering just enough content to fill the screen and continuously updating as the user scrolls. On today’s Web, virtualization breaks basic features like links and find-in-page, but hope is in sight. We’ll take an early peek at an effort to add a first-class virtual scroller to HTML, building on an exciting new platform concept called Layered APIs.
