Exploring the options for combining two function returns in Angular.js or JavaScript

Requesting help with my Angular controller. I am trying to display items from both variables x and y on the webpage, but currently it only shows items from variable y. I attempted to combine the two function result sets using .push() into the PremByClass array. Any guidance or assistance on how to achieve this would be highly appreciated.

app.controller('PremByClass', ['$scope', '$http', 'policyApi', 'lookupApi', function ($scope, $http, policyApi, lookupApi) {
    $scope.model = {};
    $scope.load.then(function () {
        function formatDate(value) {
            return value.getMonth() + 1 + "-" + value.getDate() + "-" + value.getFullYear();
        }
        $scope.PremByClass = [];
        policyApi.policy.get().then(function (t) {
            if (t) {
                policyApi.class.get().then(function (x) {
                    if (x) {
                        //Include x in $scope.PremByClass
                        $scope.PremByClass.push(x);
                        var dtEff = formatDate(t.DateEffective);
                        for (var i = 0, e = null; e = x[i]; i++) {
                            lookupApi.WCClassDesc.get(e.GovState, e.classCode, e.DescCode, dtEff).then(function (y) {
                                //The process seems correct but $scope.PremByClass neglects x
                                //Webpage only displays y data
                                $scope.PremByClass.push(y);
                            })
                        }
                    }
                })
            }
        })
    });
}]);

It appears that your x variable is stored as an array, indicating it should be displayed on the page as a list or table of objects using code similar to this:

<ul>
  <li ng-repeat="item in PremByClass[0]">
    {{item.GovState}} // {{item.classCode}}
  </li>
</ul>

Utilizing index 0 in the PremByClass array allows access to the first item pushed into it by your x variable. To enhance maintainability, consider assigning x to a more significant scope property.

To achieve this, update this line in your controller:

$scope.PremByClass.push(x);

to:

$scope.policies = x;

Then adjust your ng-repeat block to reference policies:

<ul>
  <li ng-repeat="item in policies">
    {{item.GovState}} // {{item.classCode}}
  </li>
</ul>

This adjustment will store only results from the lookupApi.WCClassDesc service/factory within the PremByClass array. You can then display them on the screen by replacing policies with PremByClass in the ng-repeat code above.
