How can I do a FULL OUTER JOIN in MySQL

undefined is not an object , can't access the Api response

Bianchi

i have a problem when trying to use the api response in my components , I fetched the api stores the response correctly but when accessing the response object I get this error

undefined is not an object (evaluating 'response.employee_name')

here is my code :



export default  function TutorsScreen ({ navigation }) {

    let [response ,setResponse] =useState();

    useEffect(()  =>  {
        fetch("https://dummy.restapiexample.com/api/v1/employee/1")
        .then(res => res.json())
        .then((jsoon)=>setResponse(jsoon.data)) },[]);

return(
    <View style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}>
            <Text
                onPress={() => navigation.navigate('Home')}
                style={{ fontSize: 26, fontWeight: 'bold' }}>
          employee salary: {response.employee_salary} </Text>
        </View>
)
}
