State management is a process of managing an application’s data. As a developer, it is important to ensure data remains consistent and synchronized across different application parts.

You’ll start by learning the state management strategies in React Native using state and props and create a real-world Funbook application using only React Native built-in solutions. You’ll learn about the Redux and MobX libraries and how these can be used to implement the like button in the app. Next, you will implement the like button using the XState library that treats the state as a finite state machine. You’ll also learn about the Jotai library that uses atomic state for state management. Finally, you’ll learn how React Query offers comfortable fetching and data mutation on the server that replaces global state management needs.

After completing this course, you will be equipped to implement complex state management functionalities, ensuring data consistency and synchronization across different application parts.

To replace existing state management libraries

What is the primary reason for the continuous emergence of new state management libraries in the React ecosystem?

What is the primary reason for the continuous emergence of new state management libraries in the React ecosystem?

They manage state naturally with `setState` or `useState`.


They wrap the state and allow subscription and reading of wrapped values.

They follow a unidirectional data flow and hold state outside of components.


They focus on the smallest possible denomination of state pieces.

To prevent unexpected crashes in the app


To replace other state management libraries

What is the purpose of configuring `Suspense` in the context of Jotai?

What is the purpose of configuring <code>Suspense</code> in the context of Jotai?

What is the purpose of the atom created below?
```
import { atom } from "jotai";
export const imageListAtom = atom([
    {
    "itemId": 1,
    "authorId": 11,
    "timeStamp": "2 hrs ago",
    "url": "...",
    "likes": "28",
    "conversations": "12"
    }, 

What is the purpose of the atom created below?
<pre><code>import { atom } from &quot;jotai&quot;;
export const imageListAtom = atom([
 {
 &quot;itemId&quot;: 1,
 &quot;authorId&quot;: 11,
 &quot;timeStamp&quot;: &quot;2 hrs ago&quot;,
 &quot;url&quot;: &quot;...&quot;,
 &quot;likes&quot;: &quot;28&quot;,
 &quot;conversations&quot;: &quot;12&quot;
 }, </code></pre>

Read-write atoms can only hold simple values or strings.


Read-write atoms do not have access to a getter function.


Read-write atoms include a setter function for write functionality.


Read-write atoms cannot access other atoms using the getter function.

How is a read-write atom different from a read-only atom in Jotai?

How is a read-write atom different from a read-only atom in Jotai?

To create an `async` atom for fetching real data from the server


To configure `Suspense` in the Jotai library

To add a write functionality to `imageListAtom`

What is the purpose of the `fetchImagesAtom` atom in the provided code?
```
export const Home = () => {
  const [json] = useAtom(fetchImagesAtom);
  const [, setAllImages] = useAtom(imageListAtom);
  useEffect(() => {
    if (json) {
      setAllImages(json);
    }
}, [json]);

What is the purpose of the <code>fetchImagesAtom</code> atom in the provided code?
<pre><code>export const Home = () =&gt; {
 const [json] = useAtom(fetchImagesAtom);
 const [, setAllImages] = useAtom(imageListAtom);
 useEffect(() =&gt; {
 if (json) {
 setAllImages(json);
 }
}, [json]);</code></pre>

 It sets up mocked image data in the app.

 It manages the actual action of liking an image.


It forces a rerender when the tab is focused.


It configures `Suspense` in the Jotai library.

How is the `useIsFocused` hook used below?
```
import { useIsFocused } from "@react-navigation/native";
export const Favorites = ({ navigation }) => {
  const isFocused = useIsFocused();
return ( 
//...

How is the <code>useIsFocused</code> hook used below?
<pre><code>import { useIsFocused } from &quot;@react-navigation/native&quot;;
export const Favorites = ({ navigation }) =&gt; {
 const isFocused = useIsFocused();
return ( 
//...</code></pre>
