jsでobjectのキーの順序を変更する

{
    address:'',
    age:'',
    client_name:'',
    customer_id:'',
    first_visit_date:'',
    prefecture:'',
}

jsのobjectのキーを自分の指定した、順序に並び替える方法。

//json並び替え key_orderの順番に並び替える
 let key_order = ['address','client_name','first_visit_date','prefecture','customer_id','age']
 let hash = {}
 let items_data = key_order.map(function(x){
   return json.items[0][x]
 })

 for (let [i,j] of zip(key_order,items_data)){
   hash[i] = j
 }
 json.items[0] = hash
