The DOM is abysmally slow for everything except one use case: displaying a simple text page with a couple of images. The core of the web is designed to display that on a 1990s computer in a single rendering pass. Everything bolted on top adds layers of complexity and indirection resulting in a laughably slow and inefficient system. The web can't even reliably animate an item in a list for laughing out loud.
