How does Vue's reactivity system compare to React's?

Vue's reactivity system is based on a dependency tracking mechanism, while React uses a virtual DOM and hooks for state management.

Can you explain how Vue's dependency tracking works?

Sure! Vue tracks dependencies during component rendering, so when a reactive property changes, only the components that depend on it are re-rendered.

What about React's hooks? How do they fit into the reactivity model?

React's hooks, like useState and useEffect, allow functional components to manage state and side effects, promoting a more functional programming style.

Which system is more efficient in terms of performance?

It depends on the use case. Vue's fine-grained reactivity can be more efficient for smaller applications, while React's virtual DOM excels in larger, complex UIs.
