以任何其他方式访问属性-data.bar2.name：

const data = {
  "bar2": {
    "address": "138/140 Gouger St, Adelaide SA 5000",
    "appStoreURL": "http://itunes.apple.com/app/idXXXXXXXXX",
    "description": "Disco Mexico, blends party vibes with fuss-free Mexican food in a small-bar setting.",
    "imgURLs": [
      "https://url",
      "https://url"
    ],
    "lat": -34.848082,
    "lon": 138.599813,
    "name": "Disco Mexico Taqueria",
    "phone": "0416 855 108",
    "status": "active",
    "venueImgURL": "https://firebasestorage.googleapis.com/v0/b/vipeeps-2018.appspot.com/o/venueImages%2FDisco_Mex_o.jpg?alt=media&token=60d76240-221c-415c-8d0d-7324d95a30ba"
  }
};
const name = data.bar2.name;
console.lo(name);
