React’s virtual DOM explained
What Is the Virtual DOM in React?
The virtual DOM is a lightweight representation of the actual DOM in memory. React updates the virtual DOM first, then synchronizes these changes with the real DOM in a process known as reconciliation. This approach minimizes direct manipulation of the DOM, improving performance.
How It Impacts Performance and Rendering
By batching updates and minimizing direct DOM manipulations, the virtual DOM significantly enhances rendering performance. This makes React particularly well-suited for applications with complex, dynamic UIs.
Angular’s two-way data binding
