Recall & Review

beginner

What is Zustand in React Native development?

Zustand is a small, fast, and scalable state management library for React and React Native apps. It helps manage app state with minimal setup and boilerplate.

How does Zustand differ from Redux?

Zustand is simpler and lighter than Redux. It requires less code, no reducers or actions, and uses hooks directly for state access and updates.

Show a basic example of creating a Zustand store.

import create from 'zustand';
const useStore = create(set => ({
  count: 0,
  increment: () => set(state => ({ count: state.count + 1 }))
}));

This creates a store with a count and an increment function.

Why is Zustand considered a lightweight alternative for state management?

Because it has a small bundle size, minimal API, no boilerplate code, and uses React hooks directly, making it easy and fast to use.

What are some benefits of using Zustand in React Native apps?

Benefits include simple API, no need for context providers, easy to learn, good performance, and flexibility to manage local and global state.

Which of the following best describes Zustand?

A A lightweight state management library using hooks

B A UI component library for React Native

C A navigation library for React Native

D A testing framework for React Native apps

Zustand is a lightweight state management library that uses React hooks.

How do you update state in Zustand?

A By dispatching actions and reducers

B By calling set function inside the store

C By using context providers

D By using Redux middleware

Zustand updates state by calling the set function provided in the store definition.

Which hook do you use to access Zustand store state?

A useContext

B useEffect

C useState

D useStore (custom hook from Zustand)

Zustand provides a custom hook (usually named useStore) to access and update state.

What is a key advantage of Zustand over Redux?

A Simpler API with less setup

B Uses reducers and actions

C Requires more boilerplate code

D Requires middleware for async

Zustand has a simpler API and requires less setup compared to Redux.

Zustand can be used to manage which types of state?

A Only local component state

B Only global app state

C Both local and global state

D Only navigation state

Zustand can manage both local and global state in React Native apps.

Explain how Zustand simplifies state management in React Native compared to Redux.

Think about how you write less code and use hooks directly.
