What are the differences between Options API and Composition API in Vue.js?

What are the main differences between Options API and Composition API in Vue.js?

The Options API organizes code by options like data, methods, and lifecycle hooks, while the Composition API allows for more flexible code organization using functions.

Can you give me an example of how to use both APIs?

Sure! In the Options API, you define a component like this: export default { data() { return { count: 0 }; }, methods: { increment() { this.count++; } } };. In the Composition API, it looks like this: import { ref } from 'vue'; export default { setup() { const count = ref(0); const increment = () => { count.value++; }; return { count, increment }; } };.

Which one is better for large applications?

The Composition API is often preferred for large applications because it promotes better code organization and reusability.

Are there any downsides to using the Composition API?

Yes, the Composition API can have a steeper learning curve for beginners and may lead to more complex code if not managed properly.
