            "firstName":"ABC"
         },
         "isdeleted":true
      }
   },
   {  
      "test":"b1",
      "system":{  
         "tenentid":"xxxxx",
         "createdByUser":{  
            "lastName":"x",
            "firstName":"ABC"

Iterate the array, add the property:

迭代数组,添加属性:

for (var i = 0; i < data.length; i++) {

我们就像编写node.js一样吗?

data.forEach(function(someData){
    someData.system={};
});

更简单的方法是:
