决定应按字符串名称显示哪个组件

import React from 'react';
import ComponentA from './ComponentA';
import ComponentB from './ComponentB';
import ComponentC from './ComponentC';

const ComponentSelector = ({ componentName }) => {
  let componentToRender;

  switch (componentName) {
    case 'A':
      componentToRender = <ComponentA />;
      break;
    case 'B':
      componentToRender = <ComponentB />;
      break;
    case 'C':
      componentToRender = <ComponentC />;
      break;
    default:
      componentToRender = null;
  }

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

export default ComponentSelector;
