What is the Vue lifecycle and why is it important?

The Vue lifecycle refers to the series of stages a Vue instance goes through from creation to destruction. It's important because it allows developers to hook into these stages to perform actions like data fetching, event handling, and cleanup.

Can you explain the different lifecycle hooks?

Sure! The main lifecycle hooks are: beforeCreate, created, beforeMount, mounted, beforeUpdate, updated, beforeDestroy, and destroyed. Each hook serves a specific purpose in the lifecycle.

What happens in the 'mounted' hook?

In the 'mounted' hook, the component is added to the DOM. It's a great place to perform actions that require the component to be fully rendered, like fetching data from an API.

How do I use these hooks in my Vue component?

You can define lifecycle hooks as methods in your Vue component. For example, you can add a mounted method like this: mounted() { // your code here }.
