How do I set up the Composition API in Vue 3?

To set up the Composition API in Vue 3, you need to create a new Vue project and install Vue 3 if you haven't already.

What are the main features of the Composition API?

The main features include reactive state management, lifecycle hooks, and the ability to organize code into reusable functions.

Can you show me a simple example?

Sure! Here's a basic example:

import { createApp, ref } from 'vue';

const App = {  
  setup() {  
    const count = ref(0);
    const increment = () => count.value++;
    return { count, increment };
  }
};

createApp(App).mount('#app');

What are the advantages of using the Composition API over the Options API?

The Composition API offers better code organization, improved type inference, and easier reuse of logic across components.
