Key Recommendations
- Use
<script setup lang="ts">for all components - Prefer
ref()overreactive()for declaring state - Use type-based prop declarations with interfaces
- Use
defineModel()for v-model (3.4+) - Destructure props reactively (3.5+) for cleaner code
- Extract composables for reusable stateful logic
