Vue.js: What is the difference between Options API and Composition API?

1// Options
2export default {
3    data() { return { count: 0 } },
4    methods: {
5        increment() { this.count++ }
6    }
7}
8
9// Composition
10import { ref } from "vue"
11const count = ref(0)
12const increment = () => count.value++
