检查myArray中的键值对是否在JSON中，如果没有，请将其添加进去

I am trying to check to see if a key,value pair in my array is found in the response JSON and if it is not, then I want to add it to the JSON.

我试图检查我的数组中的键,值对是否在响应JSON中找到,如果不是,那么我想将它添加到JSON。

$scope.myArray = [{
  "Product_type": "T"
}, {
  "Product_type": "4NB"
}, {
  "Product_type": "C"
}, {
  "Product_type": "39087NB"
}, {
  "Product_type": "16364NB"
}];

JSON response array:

JSON响应数组:

$scope.data.obj.Product = [{
  "Count": 28,
  "Product_type": "T"
}, {
  "Count": 88,
  "Product_type": "4NB"
}, {
  "Count": 20,
  "Product_type": "C"
}, {
  "Count": 3,
  "Product_type": "39087NB"
}]

In this case, the missing key,value pair would be "Product_type": "16364NB". How would I do the check and then add to the response JSON?

在这种情况下,缺失的键,值对将是“Product_type”:“16364NB”。我如何进行检查然后添加到响应JSON?

Should I iterate through the JSON and then somehow reference myArray to figure out which one is missing, then push it to the JSON?

我是否应该遍历JSON,然后以某种方式引用myArray来确定缺少哪一个,然后将其推送到JSON?

$scope.myArray.forEach(function (a, i) {						
    if ($scope.data.obj.Product.find(function(item) { return item.Product_type === a.Product_type }) === undefined) {
        $scope.data.obj.Product.push(a);							
    }
});
