JSON Boolean doesn't seem to work

Question

I'm struggling a bit with my web application

First time working with JSON for me.

Where the json looks like this

{
"Code":"310254351",
"FirstName":null,
"LastName":null,
"NewUser":true
}

I can see in my HTML that the 'NewUser' bool comes through perfectly. Somehow I cannot get is to work in JS (angular)

 $scope.checkForUserProfile = function () {
    $scope.getUserProfile();

    if ($scope.userprofile.NewUser)
    {
        $scope.showWelcome = false;
        $scope.showProfileNew = true;
    }
    else (!$scope.userprofile.NewUser)
    {
        $scope.showWelcome = true;
    }           
}

$scope.getUserProfile = function () {
    $scope.loading = true;
     $http.post('http://localhost:49165/Service1.svc/userprofile/get/').then(
        function (response) {
            $scope.userprofile = response.data;
        }, function (errResponse) {
            console.error('Error while getting user profile');
        });
    $scope.loading = false;
};

Am I missing some casting or something?

I tried several ways also this doesn't seem to work;

 if ($scope.userprofile.NewUser = true){

// do something }

Answer 1

$scope.userprofile it seems undefined. Should you want to do this:

$scope.userprofile = $scope.getUserProfile();

Answer 2

else (!$scope.userprofile.NewUser)

else doesn't take a boolean like that! Remove the bit between () .

So the if becomes:

    if ($scope.userprofile.NewUser)
    {
        $scope.showWelcome = false;
        $scope.showProfileNew = true;
    }
    else
    {
        $scope.showWelcome = true;
    }
