What is the v-once directive in Vue.js?
The v-once directive in Vue.js is used to render plain HTML elements only once. It helps improve performance by skipping re-renders.
Can you give me an example of how to use v-once?
Sure! You can use it like this: <div v-once>{{ message }}</div>. This will render the message only once.
What happens if the data changes after using v-once?
If the data changes, the v-once element will not update because it only renders once. It's great for static content.
Are there any performance benefits to using v-once?
Yes, using v-once can improve performance by reducing the number of re-renders, especially in large applications.
