如果我们在React中有两个计数器组件，我们需要复制计数器代码吗？

import React, { useState } from 'react';

const Counter = () => {
  const [count, setCount] = useState(0);

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

  const decrement = () => {
    setCount(count - 1);
  };

  return (
    <div>
      <button onClick={decrement}>-</button>
      <span>{count}</span>
      <button onClick={increment}>+</button>
    </div>
  );
};

export default Counter;

import React from 'react';
import Counter from './Counter';

const App = () => {
  return (
    <div>
      <Counter />
      <Counter />
    </div>
  );
};

export default App;
