 Functional components don't need to be wrapped with the `withIonLifeCycle` HOC as class components do.
 :::
 
+Developers can also optionally pass reactive dependencies to each lifecycle hook. These are then passed to the underlying [React useEffect hook](https://react.dev/reference/react/useEffect#useeffect):
+
+```tsx
+const [data, setData] = useState('foo');
+
+useIonViewDidEnter(() => {
+  console.log('ionViewDidEnter event fired');

 ## React LifeCycle Methods
 
 All the lifecycle methods in React (`componentDidMount`, `componentWillUnmount`, etc..) are available for you to use as well. However, since Ionic React manages the lifetime of a page, certain events might not fire when you expect them to. For instance, `componentDidMount` fires the first time a page is displayed, but if you navigate away from the page Ionic might keep the page around in the DOM, and a subsequent visit to the page might not call `componentDidMount` again. This scenario is the main reason the Ionic lifecycle methods exist, to still give you a way to call logic when views enter and exit when the native framework's events might not fire.
