A server I’m interacting with responds with the above.

I’m trying to loop through itenter code here for the For..in statement.

This is what I’m trying to do:

for (var item in response.data) {
  console.log(item.name);
}

This doesn’t work.
What went wrong?

Thank you

I GOT IT to work with the following after reading the comment:

for (var item in response.data) {
  console.log(response.data[item].name);
}

I was able to get a list of names…

Can someone dissect the response as to why it worked?

Check out: Why is using "for…in" with array iteration a bad idea?

For…in iterates through names of the properties of an object. Array items are also considered “properties”, so for..in iterates through indexes (which are 0, 1 in your case). As expected when you use response.data[0] you get first element of your array.
