To use the Composition API in Vue 3, leverage reactivity primitives like `ref` and `computed` alongside lifecycle hooks to organize reusable logic cleanly within your components.

The `<script setup>` syntax in Vue Single File Components is a compile-time syntactic sugar that exposes top-level bindings directly to the template, enabling cleaner and more performant component code without an explicit return statement.

Implement advanced UI patterns by utilizing Vue built-in components like `Transition` for animations, `Teleport` for portal rendering, `Suspense` for async dependencies, and `KeepAlive` for caching component state during route switches.

Yes, you can use TypeScript with Vue 3 `<script setup>` by adding the `lang="ts"` attribute to your SFC block, ensuring enhanced type safety and a better developer experience when defining props and emits.

Watch reactive state changes by importing the `watch` function to trigger side effects, and manage component mounting or updates by executing lifecycle hooks like `onMounted` directly within your `<script setup>` block.
