使用react钩子修改React状态属性的最佳方法

import React, { useState } from 'react';

function Counter() {
  // 初始化状态，设置初始值为0
  const [count, setCount] = useState(0);

  // 处理点击事件，更新计数值
  const handleClick = () => {
    setCount(prevCount => prevCount + 1);
  };

  return (
    <div>
      <p>当前计数: {count}</p>
      <button onClick={handleClick}>增加</button>
    </div>
  );
}

export default Counter;

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

import React, { useReducer } from 'react';

function reducer(state, action) {
  switch (action.type) {
    case 'increment':
      return { count: state.count + 1 };
    case 'decrement':
      return { count: state.count - 1 };
    default:
      throw new Error();
  }
}

function Counter() {
  const [state, dispatch] = useReducer(reducer, { count: 0 });

  return (
    <div>
      <p>当前计数: {state.count}</p>
      <button onClick={() => dispatch({ type: 'increment' })}>增加</button>
      <button onClick={() => dispatch({ type: 'decrement' })}>减少</button>
    </div>
  );
}

export default Counter;
