React钩子继承

import React, { useState, useEffect } from 'react';

// 父组件
function useCustomHook() {
  const [count, setCount] = useState(0);

  useEffect(() => {
    console.log('Count updated:', count);
  }, [count]);

  const increment = () => {
    setCount(prevCount => prevCount + 1);
  };

  return { count, increment };
}

// 子组件
function ChildComponent() {
  const { count, increment } = useCustomHook();

  return (
    <div>
      <p>Count: {count}</p>
      <button onClick={increment}>Increment</button>
    </div>
  );
}

// 使用子组件
function App() {
  return (
    <div>
      <h1>React Hook Inheritance</h1>
      <ChildComponent />
    </div>
  );
}

export default App;
