如何根据选定的下拉值动态呈现react组件

import React, { useState } from 'react';

const ComponentA = () => {
  return <div>Component A</div>;
};

const ComponentB = () => {
  return <div>Component B</div>;
};

const DynamicComponent = () => {
  const [selectedValue, setSelectedValue] = useState('');

  const handleChange = (event) => {
    setSelectedValue(event.target.value);
  };

  let componentToRender;

  if (selectedValue === 'A') {
    componentToRender = <ComponentA />;
  } else if (selectedValue === 'B') {
    componentToRender = <ComponentB />;
  }

  return (
    <div>
      <select value={selectedValue} onChange={handleChange}>
        <option value="">Select a component</option>
        <option value="A">Component A</option>
        <option value="B">Component B</option>
      </select>
      {componentToRender}
    </div>
  );
};

export default DynamicComponent;
