Which is better for performance: Vue or React?

Both Vue and React have excellent performance, but it can depend on the specific use case. Vue is often praised for its reactivity system, while React's virtual DOM can lead to efficient updates.

Can you explain how the virtual DOM works in React?

Sure! The virtual DOM is a lightweight copy of the actual DOM. When changes occur, React updates the virtual DOM first, then compares it to the real DOM to determine the most efficient way to update the UI.

What about Vue's reactivity system?

Vue's reactivity system uses a dependency tracking mechanism. When data changes, Vue knows which components depend on that data and only re-renders those components, making it very efficient.

Are there any benchmarks comparing their performance?

Yes, there are several benchmarks available online that compare the performance of Vue and React in various scenarios. Generally, both frameworks perform well, but the results can vary based on the specific tasks.
