如何知道函数组件中的“子”属性组件类型？

import React, { Children } from 'react';

function ParentComponent({ children }) {
  Children.map(children, child => {
    if (React.isValidElement(child)) {
      console.log(child.type); // 子组件的类型
    }
  });

  return <div>{children}</div>;
}

function ChildComponent() {
  return <div>子组件</div>;
}

function App() {
  return (
    <ParentComponent>
      <ChildComponent />
      <ChildComponent />
    </ParentComponent>
  );
}
