在reactjs中将字符串参数从一个组件传递到另一个组件

// ParentComponent.js
import React from 'react';
import ChildComponent from './ChildComponent';

class ParentComponent extends React.Component {
  render() {
    const message = "Hello, World!";
    return (
      <ChildComponent message={message} />
    );
  }
}

export default ParentComponent;

// ChildComponent.js
import React from 'react';

function ChildComponent(props) {
  return (
    <div>{props.message}</div>
  );
}

export default ChildComponent;
