class App extends React.Component {
    constructor() {
        super();
        this.state={
            monsters:
                []
        };
    }
    componentDidMount() {
        fetch('http://jsonplaceholder.typicode.com/users')
            .then(res => res.json())
            .then((data) => {
                this.setState({ monsters: data })
            })
    }
    render() {
     return(
         <div>
             <CardList monters={this.state.monsters}/>
         </div>
     )
 }
}
export default App;

和cardlist.jsx
请指导我该怎么做

import './card-list.css'


export const CardList=(props) => (

     <div className='card-list'>{props.monsters.map(monster =>(<h1 key={monster.id}>{monster.name}</h1>))}

    </div>
);```
