How can I reduce re-renders in my Vue.js application?

To reduce re-renders in Vue.js, you can use techniques like computed properties, watchers, and the v-once directive.

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, reducing unnecessary re-renders.

Can you give an example of using the v-once directive?

Sure! The v-once directive renders an element and its children only once, preventing future updates. For example: <div v-once>{{ message }}</div>.

Are there any performance tools to analyze re-renders?

Yes, you can use Vue Devtools to analyze component re-renders and identify performance bottlenecks.
