What are some reactivity optimizations in Vue.js?

Vue.js offers several reactivity optimizations, such as using computed properties, watchers, and the v-once directive to minimize unnecessary re-renders.

How do computed properties help with performance?

Computed properties cache their results and only re-evaluate when their dependencies change, reducing the number of calculations.

Can you explain how watchers work?

Watchers allow you to perform asynchronous or expensive operations in response to data changes, helping to optimize performance.

What is the v-once directive?

The v-once directive renders an element and its children only once, preventing Vue from re-rendering them on subsequent updates.

Are there any other tips for optimizing Vue.js applications?

Yes, consider using the key attribute for list rendering, lazy loading components, and minimizing the use of inline functions.
