React fetch data of objects and render

Question

I am doing a peronal project in React.js. I am fethcing data and I want to render that data in the screen. I am having issues with it as it is an object the data. My first try was with map, but it didn't work. This is the code:

import { useEffect, useState } from 'react';

const Home = () => {
  const [result, setResult] = useState([]);

  useEffect(() => {
    fetch('https://www.betright.com.au/api/racing/todaysracing')
      .then(res => {
        return res.json();
      })
      .then((data) => {
        setResult(data);
        console.log('data useEffect', data)
      },
      (err) => {
        return console.error(err)
      })
  }, [])
  console.log('result', result)
  return (
    <>
    <h1>Upcoming Racing</h1>
    {result?.map((value, key) => (
        <table key={key}>            
            <thead>
                <tr>
                    <th>Greyhound</th>
                    <th>Harness</th>
                    <th>Throughbred</th>
                </tr>
            </thead>
            <tbody>
                <tr>
                    <td>{value?.Greyhound?.Venue}</td>
                    <td>{value?.Harness?.Venue}</td>
                    <td>{value?.Throughbred?.Venue}</td>
                </tr>
            </tbody>
        </table>
    ))}
    </>
  );
}

export default Home;

Then I tried with Object.keys/values/entries and I couldn't make it work either way:

{Object.keys(result).map((value, key) => (
        <li key={key}>
            <span>key: {key} dogs: {result[value].VenueId}</span>
        </li>
    ))}

My idea is to display in a list the first 5 races of each dog This is the whole code in sandbox. This is the console.log of data.:

{Throughbred: Array(7), Harness: Array(6), Greyhound: Array(10)}
Greyhound: Array(10)

Answer 1

You can use entries to solve this, it'll give key and value as an array.

{
  Object.entries(result).map(([key, value]) => (
    <li key={key}>
      <span>
        key: {key}
        dogs: {value.slice(0, 5).map((dog) => dog.VenueId)}
      </span>
    </li>
  ));
}
