Demystify the V DOM
summary
Live codes a tiny React clone in plain JavaScript that actually renders to the DOM, implements createElement and renderNode, a Component class with setState that merges state and caches baseElement, and an update/diff that compares child lengths and appends the new item every ~2 seconds. Uses browser paint flashing to show it avoids full tree repaint. The demo runs in the browser, prints logs, and visibly updates without re-rendering the whole list.
