Vue.js 3 Composition API

The Composition API provides better logic reuse and code organization in Vue.js.

import { ref, computed, onMounted } from 'vue'

export default {
    setup() {
        const count = ref(0)
        const double = computed(() => count.value * 2)
        
        onMounted(() => {
            console.log('Component mounted')
        })
        
        return {
            count,
            double
        }
    }
}
