Optimize React performance with `useCallback`. Prevent unnecessary child component re-renders by memoizing functions passed as props, ensuring stable references.
Boost React performance with `useMemo`. Cache results of expensive computations or object creations, preventing re-computation on every render for efficiency.
Master React's `useReducer` for complex state management. Centralize logic for states with multiple sub-values or intricate transitions, enhancing predictability.
Build a `useLocalStorage` React hook to easily persist component state in the browser's local storage. Handles initial values, JSON serialization, and updates.
Create a custom React `useDebounce` hook to delay value updates, perfect for search inputs, API calls, and other performance-sensitive operations, preventing excessive re-renders.
Implement a flexible `useEventListener` React hook to easily attach and clean up event listeners to the window, document, or any DOM element, simplifying event handling.
Create a `useFetch` React hook to handle data fetching from APIs, managing loading states, error handling, and the fetched data in a clean, reusable pattern.
Develop a `useArray` React hook to streamline operations on an array state, providing convenient functions for adding, removing, updating, and clearing elements.
Enhance web application security by implementing critical HTTP response headers like HSTS, X-Frame-Options, and others in your Express.js server for robust protection.
Strengthen your Express.js application's session management by properly configuring `HttpOnly`, `Secure`, and `SameSite` flags for all cookies to prevent common attacks.
Learn to implement a secure Cross-Origin Resource Sharing (CORS) policy in your Express.js API to control access from different origins and protect your resources effectively.
