The real DOM gets synced by ‘react-dom’ THE DOM. To learn more, see our tips on writing great answers. While the shadow DOM encapsulates the implementation of custom web components, the virtual DOM is used to differentiate changes and more effectively re-render UIs. You may pass any props you like to the root. That means that React events won’t work inside the shadowed part. There are some generic solutions to this algorithmic problem of generating the minimum number of operations to transform one tree into another. We can see it as a subtree or as a separate DOM for an element. Like an
