Best Practices

1. Composition API First - Use Composition API for better TypeScript support and reusability
2. Smart Component Splitting - Break down components by feature, not just size
3. Proper Ref Usage - Use ref() for primitives, reactive() for objects, shallowRef() for performance
4. Async Component Loading - Leverage defineAsyncComponent() for code splitting
5. Teleport for Modals - Use Teleport for overlays to avoid z-index issues
6. Provide/Inject Wisely - Use for cross-cutting concerns, not general state management
7. v-memo for Lists - Optimize large lists with v-memo directive
8. Proper Key Usage - Always use stable, unique keys in v-for
9. Event Handler Cleanup - Clean up event listeners in onUnmounted()
10. TypeScript Integration - Use proper types for props, emits, and refs
