compare to object angular js - angularjs

Question

i have a problem with AngularJS I receive from api json that json contains a prod url and url prerpod I would make calls to these APIs to retrieve a new one json then compare the results to validate which are the same as the problem is that I have a 200 aPI test how can I do. Thank you in advance
ps I think the test objects with the method equals.
i have 100 object like this:
{
"ID": "1",
"URL_preprod": "url1",
"Preprod_bis": "url2",
"prod": "url3",
}
i need to check if the result of call is equals for each object.
function callAtTimeout() {
if ($scope.preprod && $scope.preprodBis) {
angular.equals($scope.preprod,$scope.preprodBis);
$scope.msg = "equals";
}}
$scope.test = function() {
if (tnrArray) {
for (var i = 0; i < tnrArray.length; i++) {
var urlPreprod = tnrArray[i].URL_preprod;
console.log(urlPreprod);
$http.get(urlPreprod).success( function(response) {
$scope.preprod = response;
console.log(response);
});
var urlPreprodBis = tnrArray[i].Preprod_bis;
console.log(urlPreprodBis);
$http.get(urlPreprodBis).success( function(response) {
$scope.preprodBis = response;
console.log(response);
});
$timeout(callAtTimeout, 3000);
}

Answer 1

var response1;
$http.get("/your/url").then(function(response) {
response1 = response;
return $http.get(response.prodUrl);
}).then(function(prodResponse) {
console.log(prodResponse);
console.log(_.isEqual(response1 , prodResponse)); // uses lodash
}).catch(function(badResponse) {
console.log("oops something went wrong", badResponse);
})
this should work - lodash is used to check for equality
TO DO THIS FOR 200 URLs ASYNCHRONOUSLY ...
var urlList = ['/path/url1','/path/url2','/path/url3'];
angular.forEach(urlList, function(url) {
var response1;
$http.get(url).then(function(response) {
response1 = response;
return $http.get(response.prodUrl);
}).then(function(prodResponse) {
console.log(prodResponse);
console.log(angular.equals(response1 , prodResponse));
}).catch(function(badResponse) {
console.log("oops something went wrong", badResponse);
})
});
