❓ Frequently Asked Questions (FAQ)
Q What is Vue.js 3?
Vue.js 3 is a progressive JavaScript framework used for building web user interfaces. It provides reactive data binding, component-based architecture, and official tooling for routing (Vue Router) and state management (Pinia).
Q What is the difference between Options API and Composition API?
The Options API organizes component logic into options object properties (data, methods, computed), whereas the Composition API allows grouping component logic by logical feature using functions (ref, computed, watch), making code much cleaner and reusable via Composables.
