如何使用Express对JSON响应进行排序

Question

I'm wondering if is there any way to sort a JSON response with Express JS

my JSON file looks like with Postman :

{
"id":"",
"fname":"",
"lname":"",
"country":"",
"phonen":""
}

and I want to change the order and take phonen to the top.

like

   {
    "id":"",
    "phonen":"",
    "fname":"",
    "lname":"",
    "country":""
    }
