What is the Vue 3 Composition API and how do I use it?

The Vue 3 Composition API is a new way to organize and reuse code in Vue components. It allows you to use reactive state and lifecycle hooks in a more flexible manner.

Can you give me an example of how to create a simple component using the Composition API?

Sure! Here's a basic example:

import { ref } from 'vue';

export default {
  setup() {
    const count = ref(0);
    const increment = () => count.value++;

    return { count, increment };
  }
};

This creates a reactive count variable and an increment function.

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

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

Are there any resources or tutorials you recommend for learning more about the Composition API?

Yes! The official Vue documentation is a great place to start. Additionally, there are many online tutorials and courses that cover practical examples.
