Vue 3 vs React: Which One Has Better Performance?

Which framework has better performance, Vue 3 or React?

Both Vue 3 and React have made significant improvements in performance. Vue 3 uses a virtual DOM and has a more efficient reactivity system, while React has optimized rendering with hooks and concurrent mode. It often depends on the specific use case.

Can you explain how the virtual DOM works in Vue 3?

Sure! The virtual DOM in Vue 3 is a lightweight representation of the actual DOM. When changes occur, Vue updates the virtual DOM first, then compares it with the real DOM to determine the minimal number of changes needed, which enhances performance.

What about the size of the frameworks? Does that affect performance?

Yes, the size of the framework can impact performance, especially in initial load times. Vue 3 is generally smaller than React, which can lead to faster loading in applications where size is a critical factor.

Are there any benchmarks comparing their performance?

Yes, there are several benchmarks available online that compare the performance of Vue 3 and React in various scenarios. These benchmarks often show that while both frameworks perform well, the results can vary based on the specific tasks and configurations used.
