How does Vue 3's reactivity system impact performance?

Vue 3's reactivity system is designed to be more efficient than its predecessor, Vue 2. It uses a Proxy-based implementation, which allows for better tracking of dependencies and reduces the overhead of reactivity.

What are the main benefits of using the Proxy-based system?

The Proxy-based system allows for more granular reactivity, meaning that only the components that depend on changed data will re-render. This leads to improved performance, especially in large applications.

Are there any downsides to this new system?

One potential downside is that the Proxy API is not supported in Internet Explorer, which may affect compatibility for some users. Additionally, developers need to be aware of how reactivity works to avoid common pitfalls.

How can I optimize my Vue 3 application for better performance?

You can optimize your Vue 3 application by using techniques like lazy loading components, utilizing computed properties effectively, and minimizing the use of watchers where possible.
