I have a conditional html page and a conditional api.

GET request for user data in my api looks like this:

```
URL: {host}/user
Method: GET

Headers
- Content-Type: application/json
- Authorization: Bearer {token}

```

And the response:

```
Status: 200
Content-Type: application/json
Body:
{
    "first_name": "Ivan",
    "last_name": "Ivanov",
    "phone": "89001234567",
    "document_number": "1224567890"
}

```

How I can send the requests and output response data using XMLHttpRequest?

I try to use `xhr.response()` and it's work good, but when I try to `xhr.response()['first_name']` it don't work properly
