Vue.js Reactivity vs React

What are the main differences between Vue.js reactivity and React's state management?

Vue.js reactivity is based on a reactive data model, where changes to data automatically update the DOM. In contrast, React uses a virtual DOM and requires explicit state updates through hooks or setState.

Can you explain how Vue's reactivity system works?

Sure! Vue's reactivity system uses getters and setters to track dependencies. When a reactive property changes, Vue automatically re-renders the components that depend on it.

How does React handle state updates?

React uses a virtual DOM to optimize updates. When state changes, React re-renders the component and compares the new virtual DOM with the previous one to determine what needs to be updated in the actual DOM.

Which one is better for performance?

It depends on the use case. Vue's reactivity can be more efficient for smaller applications, while React's virtual DOM is optimized for larger applications with complex UIs.
