How can I optimize performance in Vue's reactivity system?

To optimize performance in Vue's reactivity system, consider using computed properties, watch for changes efficiently, and minimize the number of reactive properties.

What are computed properties and how do they help?

Computed properties are cached based on their dependencies. They only re-evaluate when their dependencies change, which can significantly reduce unnecessary computations.

Are there any specific techniques to reduce reactivity overhead?

Yes, you can use the v-once directive for static content, and avoid deep watchers unless necessary. Also, consider using shallowReactive for objects that don't require deep reactivity.

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

Vue's reactivity is based on getters and setters, while React uses a virtual DOM and state management. Vue can be more efficient for certain scenarios due to its fine-grained reactivity.
