React useDebounce Hook for Input Optimization

Improve performance by debouncing any value in React, commonly used for search inputs or form fields to delay updates until user pauses.

import { useState, useEffect } from 'react';

function useDebounce(value, delay) {
  const [debouncedValue, setDebouncedValue] = useState(value);

  useEffect(() => {
    const handler = setTimeout(() => {
      setDebouncedValue(value);
    }, delay);

    return () => {
      clearTimeout(handler);
    };
  }, [value, delay]);

  return debouncedValue;
}
How it works: This `useDebounce` hook delays updating a value for a specified `delay` period. It's particularly useful for preventing excessive re-renders or API calls, for instance, when a user types into a search input. The hook returns the debounced value, which only updates after the user has stopped typing for the defined delay, ensuring smoother performance and reduced resource usage.
