How can I optimize re-renders in Vue.js?

To optimize 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 explain how watchers work?

Watchers allow you to perform actions in response to data changes. They can be used to optimize performance by limiting updates.

What is the v-once directive?

The v-once directive renders plain HTML elements only once, preventing Vue from re-rendering them on subsequent updates.
