What are the main advantages of using Vue.js over vanilla JavaScript?

Vue gives you declarative data binding, automatic DOM updates, and cleaner code organization than hand-written vanilla JavaScript.

Key benefits:

• Data binding - connect data to views declaratively
• Reactivity - DOM updates automatically when data changes
• Templates - embed expressions directly in HTML
• Directives - powerful shortcuts for common patterns
• Less code - no manual getElementById or innerHTML manipulation

Vue.js handles the "how" of DOM updates so you can focus on the "what" of your application logic.
