Javascript JSON變量父

Question

我正在研究離子1應用程序，我不知道是否有辦法，但例如，在這裏，有沒有一種方法可以動態地分配此對象中的父項，具體取決於變量？

var contact = { 
    "Name": "John Doe", 
    "available": true, 
     Variable: [ 
     { 
      "Location": "Home", 
      "Number": "33" 
     }, 
     { 
      "Location": "Work", 
      "Number": "22" 
     } 
    ] 
}; 

比方說變量=「朋友」那

var contact = { 
    "Name": "John Doe", 
    "available": true, 
    "Friends": [ 
     { 
      "Location": "Home", 
      "Number": "33" 
     }, 
     { 
      "Location": "Work", 
      "Number": "22" 
     } 
    ] 
}; 

我知道我可以使用ES6，計算出的屬性名稱[變量]，但他們沒有工作的舊設備。有沒有其他方法？

只是普通的老

var contact = { 
    "Name": "John Doe", 
    "available": true, 
}; 
contact[Variable] = [ 
    { 
     "Location": "Home", 
     "Number": "33" 
    }, 
    { 
     "Location": "Work", 
     "Number": "22" 
    } 
]
