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

The Vue.js Composition API is a new way to organize and reuse logic 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 reusability of logic, and easier testing. It also helps manage complex components more effectively.

Are there any downsides to using the Composition API?

One downside is that it can be more complex for beginners to grasp compared to the Options API. It may also lead to less readable code if not structured properly.
