Javascript Programming Tutorials, Guides & Best Practices

• Simplicity: Create stores using a straightforward API without the need for reducers or action types.
• Performance: Optimized for performance with selective rendering and minimal re-renders.
• Flexibility: Supports custom hooks, middleware, and integration with other libraries.
• No Providers: Unlike Redux, Zustand doesn't require wrapping your app with context providers.

These features make Zustand an attractive choice for developers looking to manage state in a more concise and efficient manner.

React.lazy allows you to lazy-load components, and Suspense provides a fallback while the component is being loaded.

import React, { Suspense } from 'react';

const LazyComponent = React.lazy(() => import('./LazyComponent'));

function App() {
  return (
    <div>
      <Suspense fallback={<div>Loading...</div>}>
        <LazyComponent />
      </Suspense>
    </div>
  );
}

export default App;

Here’s an example of how to use the useFetch hook in a React component to fetch and display data.

import React from 'react';
import useFetch from './useFetch'; // Ensure correct import path

function UserList() {
    const { data, loading, error } = useFetch('https://jsonplaceholder.typicode.com/users');

    if (loading) return <p>Loading...</p>;
    if (error) return <p>Error: {error.message}</p>;

    return (
        <ul>
            {data.map(user => (
                <li key={user.id}>{user.name}</li>
            ))}
        </ul>
    );
}

export default UserList;
