渲染嵌套数据（来自另一个数组的 object 中的数组的对象）来自后端 - ReactJS (JSX)

Question

I have JSON data i am trying to render to the front end of my application. and I am trying to get the name of all the objects inside the betTypes array to the front end as a List. So far, I am only able to query a single object from the nested array.

const data = {
  games: [
    {
      name: 'BlackJack',
      slug: 'American Blackjack',
      category: 'Card games',
      image: '/images/bj.jpg',
      betTypes: [
        {
          name: 'Flush',
          det: 'Flush',
          category: 'American Blackjack',
          description:
            'The player’s two initial cards and dealer’s first cards are all of the same suits and have different values (it is also valid if two of the three cards are of the same value)',
          image: '',
        },
        {
          name: 'Mixed Color Pair',
          det: 'MXP',
          category: 'American Blackjack',
          description:
            'When the player gets two initial cards as a pair (same value) of different colour and different suit.',
          image: '',
        },
      ],
    }, 
},

This is what my front-end code looks like

function GameScreen() {
  const params = useParams();
  const { slug } = params;

  const [{ loading, error, game }, dispatch] = useReducer(reducer, {
    game: [],
    loading: true,
    error: '',
  });
  // const [games, setGames] = useState([]);
  useEffect(() => {
    const fetchData = async () => {
      dispatch({ type: 'FETCH_REQUEST' });
      try {
        const result = await axios.get(`/api/games/slug/${slug}`);
        dispatch({ type: 'FETCH_SUCCESS', payload: result.data });
      } catch (err) {
        dispatch({ type: 'FETCH_FAIL', payload: err.message });
      }

      //setGames(result.data);
    };
    fetchData();
  }, [slug]);

  return loading ? (
    <div>
      <LoadingSpin />
    </div>
  ) : error ? (
    <div>{error}</div>
  ) : (
    <div>
      <Row>
        <Col md={12}>
          <h1>{game.name}</h1> <hr />
          <img className="img-large" src={game.image} alt={game.name} />
        </Col>
        <Col md={3}>
          <ListGroup>
            <ListGroup.Item style={{ marginTop: '10px' }}>
              <h6>{game.betTypes[3].name}</h6>
            </ListGroup.Item>
          </ListGroup>
        </Col>
        <Col md={3}></Col>
      </Row>
    </div>
  );
}

I need help sorting it out please.

    <ListGroup>
         {game.betTypes.map((item)=>
            <ListGroup.Item key={item.name} style={{ marginTop: '10px' }}>
                <h6>{item.name}</h6>
            </ListGroup.Item>)
         }
    </ListGroup>
