What is Vue reactivity and how does it work?

What is Vue reactivity and how does it work?

Vue reactivity is a system that allows Vue to automatically update the DOM when the underlying data changes. It uses a dependency tracking mechanism to observe changes in data properties.

Can you explain how Vue's reactivity differs from React's?

Sure! Vue uses a reactive data model with getters and setters, while React relies on a virtual DOM and state management to trigger updates.

What are some common pitfalls when working with Vue reactivity?

Common pitfalls include mutating reactive properties directly, not using Vue.set for adding new properties, and misunderstanding how reactivity works with arrays.

How can I optimize performance when using Vue reactivity?

You can optimize performance by using computed properties, watchers, and avoiding unnecessary re-renders by managing component state effectively.
