Mastering React Hooks in 2025

React Hooks have revolutionized how we write React components. In this post, we’ll explore the most powerful patterns and best practices for using Hooks in 2025.

The Power of Hooks

Hooks let you use state and other React features without writing classes. Here’s a quick example:

import { useState, useEffect } from 'react';

function Counter() {
  const [count, setCount] = useState(0);
  
  useEffect(() => {
    document.title = `You clicked ${count} times`;
  }, [count]);

  return (
    <div>
      <p>You clicked {count} times</p>
      <button onClick={() => setCount(count + 1)}>
        Click me
      </button>
    </div>
  );
}

Advanced Patterns

Custom Hooks

Custom Hooks let you extract component logic into reusable functions:

function useWindowWidth() {
  const [width, setWidth] = useState(window.innerWidth);
  
  useEffect(() => {
    const handleResize = () => setWidth(window.innerWidth);
    window.addEventListener('resize', handleResize);
    return () => window.removeEventListener('resize', handleResize);
  }, []);
  
  return width;
}

Performance Optimization

Use useMemo and useCallback to optimize performance:

const memoizedValue = useMemo(
  () => computeExpensiveValue(a, b),
  [a, b] // Only recompute when a or b changes
);

const memoizedCallback = useCallback(
  () => {
    doSomething(a, b);
  },
  [a, b],
);

Conclusion

React Hooks provide a more direct API to the React concepts you already know. They solve a wide variety of seemingly unconnected problems in React that we’ve encountered over five years of writing and maintaining components.
