 The lifecycles are defined the same way Vue lifecycle methods are - as functions at the root of your Vue component:
 
 ```tsx

 ### Composition API Hooks
 
 These lifecycles can also be expressed using Vue 3's Composition API:
 
 ```tsx
+<script setup lang="ts">
 import { IonPage, onIonViewWillEnter, onIonViewDidEnter, onIonViewWillLeave, onIonViewDidLeave } from '@ionic/vue';
-import { defineComponent } from 'vue';
