Question

私は名前と電子メールを持つユーザーの配列を持っています。私はUserboxこの

return(<div>{  
       users.map((user)=>{ 
        return <UserBox key={user.name} user={user}></UserBox>; 
       }) 
       } 
       </div> 
      ); 

のように、この配列をループしていた親コンポーネントで この

return (
      <p> 
       {this.props.user.name} {this.props.user.rating} 
      </p> 
     ); 

と子コンポーネントですが、私はこのエラーをあなたに

を取得していますユーザーボックスコンポーネント：

return (
    <p> 
    {this.props.user.name} {this.props.user.rating} 
    </p> 
); 

this.props.user.nameまたはthis.props.user.ratingが文字列なくオブジェクトであることを確認します。
