在不知道其结构的情况下显示React组件

import React from 'react';

function App({ componentType }) {
  let Component;
  
  if (componentType === 'A') {
    Component = <ComponentA />;
  } else if (componentType === 'B') {
    Component = <ComponentB />;
  } else {
    Component = <ComponentDefault />;
  }
  
  return (
    <div>
      {Component}
    </div>
  );
}

import React from 'react';

const componentMap = {
  A: ComponentA,
  B: ComponentB,
};

function App({ componentType }) {
  const Component = componentMap[componentType] || ComponentDefault;
  
  return (
    <div>
      <Component />
    </div>
  );
}
