What are the differences in reactivity between Vue 2 and Vue 3?
In Vue 3, reactivity is based on the Proxy API, which allows for better performance and more flexible reactivity compared to Vue 2's Object.defineProperty.
Can you explain how the Proxy API improves performance?
The Proxy API allows Vue 3 to track changes more efficiently by intercepting operations on objects, reducing the need for deep observation.
What about the composition API? How does it relate to reactivity?
The Composition API in Vue 3 allows developers to organize code better and manage reactivity more intuitively, making it easier to share logic across components.
Are there any drawbacks to using the new reactivity system?
While the new system is more powerful, it can introduce complexity for developers who are used to the Options API in Vue 2.
