What are the lifecycle methods in Vue.js hooks?

In Vue.js, lifecycle methods are hooks that allow you to run code at specific stages of a component's lifecycle. They include methods like beforeCreate, created, beforeMount, mounted, beforeUpdate, updated, beforeDestroy, and destroyed.

Can you explain the difference between mounted and created?

Sure! The created hook is called after the instance is created, but before it is mounted to the DOM. This is where you can set up data and make API calls. The mounted hook is called after the component is mounted, meaning it is now in the DOM, which is a good place to interact with the DOM or perform actions that require the component to be visible.

When should I use beforeDestroy?

You should use beforeDestroy to clean up any resources, such as timers or event listeners, before the component is destroyed. This helps prevent memory leaks.

Are there any hooks specific to Vue 3?

Yes, Vue 3 introduced the Composition API, which includes new lifecycle hooks like onBeforeMount, onMounted, onBeforeUpdate, onUpdated, onBeforeUnmount, and onUnmounted. These hooks work similarly but are used within the setup function.
