# 데이터 가지고 놀기(응용)2

다음과 같은 데이터가 있다고 해봅시다. \
이런것은 나중에 API문서 등등 데이터를 받오는 것이다 라고 생각해주세요.

```javascript
// data.json
{
    "family": [
        {
            "global" :[
                {

                    "link": "https://english.miraeassetdaewoo.com/"
                },
                {

                }
