Im building a app using a country api and which displays information such as name, population and region of a country. I want to display the languages, currencies and borders with the country. Ive tried to map the data to display the borders but it's saying map is undefined.
<div>
// this works and displays
<h1>{info.name}</h1>
<p>Population: {info.population}</p>
<p>Region: {info.region}</p>
<p>Capital: {info.capital}</p>
<h4>Languages:</h4>
// this gives the error 'cannot map of undefined'<ul>
{info.borders.map((border) => {
return <li key={border.name}>{border.name}</li>; })}
</ul>
</div>
here is the response data i'm using
data:
name: "Brazil"
topLevelDomain: [".br"]
alpha2Code: "BR"
alpha3Code: "BRA"
callingCodes: ["55"]
capital: "Brasília"
altSpellings: (4) ["BR", "Brasil", "Federative Republic of Brazil", "República Federativa do Brasil"]
region: "Americas"
subregion: "South America"
population: 206135893
latlng: (2) [-10, -55]
demonym: "Brazilian"

gini: 54.7
timezones: (4) ["UTC-05:00", "UTC-04:00", "UTC-03:00", "UTC-02:00"]
borders: (10) ["ARG", "BOL", "COL", "GUF", "GUY", "PRY", "PER", "SUR", "URY", "VEN"]
nativeName: "Brasil"
numericCode: "076"
currencies: [{…}]
languages: [{…}]
Below is how I'm getting the data
const Infopage = () => {
const [info, setInfo] = useState({});
const code = useParams().alpha3Code;
useEffect(() => {
console.log('info');
axios
.get(`https://restcountries.eu/rest/v2/alpha/${code}`)
.then((response) => {
console.log(response);
setInfo(response.data);
});
// eslint-disable-next-line react-hooks/exhaustive-deps
}, []);
return (
<div>
<CountryInfo info={info} />
</div>
);
};
export default Infopage;
Ive tried this with the same issue
const [info, setInfo] = useState({});
const [isLoading, setIsLoading] = useState(false);
const code = useParams().alpha3Code;
useEffect(() => {
const fetchData = async () => {
setIsLoading(true);
const result = await axios.get(
`https://restcountries.eu/rest/v2/alpha/${code}`
);
setInfo(result.data);
setIsLoading(false);
};
fetchData();
}, [code]);
return (
<div>{isLoading ? <h1>Loading...</h1> : <CountryInfo info={info} />}</div>
