VisualizaçõesFetch data changing on reload from array to undefined
I'm getting some weird error. Just starting with typescript. When i write console.log(data) for the first time i get an array with objects inside. The problem occurs when i reload the webpage without touching anything. My console log returns undefined.
const Home = (): JSX.Element => {
const [data, setData] = useState<any>();
const [loading, setLoading] = useState<boolean>(true);
const fetchApi = () => {
fetch("https://fakestoreapi.com/products")
.then((res) => {
return res.json();
})
.then((data) => setData(data));
console.log(data)
};
useEffect(() => {
fetchApi();
setLoading(false);
}, []);
return(
<div>
</div>
)
};
Return of first console.log
After reload

you need to console.log inside "then"
.then((data) => {
setData(data));
console.log(data)
})
if you console.log the data state under setData it will show undefined, you can console.log(data) state inside useEffect after fetchApi()
