React `useMediaQuery` Hook for Responsive Components

Build truly responsive React components by reacting to CSS media queries dynamically with the `useMediaQuery` hook, adapting UI to screen sizes.

import { useState, useEffect } from 'react';

function useMediaQuery(query) {
  const [matches, setMatches] = useState(false);

  useEffect(() => {
    const media = window.matchMedia(query);
    if (media.matches !== matches) {
      setMatches(media.matches);
    }
    const listener = () => setMatches(media.matches);
    media.addEventListener('change', listener);
    return () => media.removeEventListener('change', listener);
  }, [matches, query]);

  return matches;
}

// Example Usage:
// function ResponsiveText() {
//   const isLargeScreen = useMediaQuery('(min-width: 768px)');
//   return (
//     <p style={{ fontSize: isLargeScreen ? '24px' : '16px' }}>
//       {isLargeScreen ? 'Large Screen Text' : 'Small Screen Text'}
//     </p>
//   );
// }

How it works: This hook allows your React components to respond to CSS media queries in real-time. It takes a media query string as input and returns a boolean indicating whether the query currently matches. It uses `window.matchMedia` and an event listener to update the state whenever the media query's status changes, enabling dynamic styling or component rendering based on screen size.
