What is the difference between Shadow DOM and Virtual DOM?
The Shadow DOM is a browser technology designed primarily for scoping variables and CSS in web components. The Virtual DOM is a concept implemented by libraries in JavaScript on top of browser APIs.
The key differences in a table format shown below:
| Feature | Shadow DOM | Virtual DOM |
|---|---|---|
| Purpose | Encapsulation for Web Components | Efficient UI rendering |
| Managed by | Browser | JS frameworks (e.g., React) |
| DOM Type | Part of real DOM (scoped) | In-memory representation |
| Encapsulation | Yes | No |
| Use Case | Web Components, scoped styling | UI diffing and minimal DOM updates |
