如何遍历主要 object 内的对象内的数组

Question

I have an API: https://www.gov.uk/bank-holidays.json

It contains an object, which contains 3 keys (Division) whose value is also an object and it includes an array showing holiday Details (events). I want to print the "title" and 'date' from it for each Division. Below is the code. How to render the data for title and date inside the Holiday.js?

     export default function App() {
  const [data, setData] = useState([]);

  const fetApi = () => {
    fetch("https://www.gov.uk/bank-holidays.json")
      .then((res) => res.json())
      .then((items) => setData(items));
  };

  useEffect(() => {
    fetApi();
  }, []);

  return (
    <div className="App">
      <Holidays data={Object.entries(data)} />
    </div>
  );
}

/ / Holiday.js

const Holidays = ({ data }) => {
  // console.log(data);
  return (
    <div>
      <ol>
        {data.map((item, i) => {
          return (
            <li key= {i}>
              <div>title:</div>    //render title here
               <div>Date :</div>    //render date here
           </li>
          );
        })}
      </ol>
    </div>
  );
};

Answer 1

Change Holliday Element into: (explanation on comments)

const Holidays = ({ data }) => {
  // console.log(data);
  return (
    <div>
      <ol className="App">
        {data.map((item, i) => {
          // since you are passing Object.entries, the first parameter is the key
          // and the second one are the values
          const [key, obj] = item;

          // you then just have to map the event inside the values
          return obj.events.map((o, index) => (
            <li key={index}>
              <div>title: {o.title}</div>
              <div>Date : {(o.date)}</div>
            </li>
          ));
        })}
      </ol>
    </div>
  );
};

replace your Holiday comonent with this

const Holidays = ({ data }) => {
  const ListItem = (array) => {
    console.log(array);
    return array[1].events.map((item, i) => {
      return (
        <li key={i}>
          <div>title: {item.title}</div>
          <div>Date :{item.date}</div>
        </li>
      );
    });
  };
  return (
    <div>
      <ol>{data.map((array) => ListItem(array))}</ol>
    </div>
  );
};

export default Holidays;
