How to optimize performance in Vue.js applications?

Vue.js provides several techniques to optimize performance, such as:

• Virtual DOM: Vue's reactive system and virtual DOM efficiently update only the components that need to be updated.
• Keep components small and focused: Split your application into smaller, reusable components.
• Use v-if and v-show wisely: Choose between them based on whether the element will be frequently toggled.
• Leverage v-for and :key: When rendering lists, use v-for with a unique :key to improve rendering efficiency.
