score:0
Accepted answer
you can check if property exits or not: {res.age ? res.age : ''}
score:0
below structure of data looks weird :
{
["name": "max", "age":15, "country": 1],
["name": "muster", "country": 56],
["name": "test", "age": 5, "country": 5]
}
but, you can use a safe operator
for that :
{res?.age ?? ''} // empty string will be returned in case res == null or undefined
