The method 'push' is not compatible with this object

Question

The method 'push' is not compatible with this object

While working with AngularJS, I encountered an issue when trying to insert a new value into an existing JSON object. The error message I received was:

"Object doesn't support property or method 'push'"

Below is the code snippet I am using:

$scope.addStatus = function (text) {          
          $scope.application.push({ 'status': text }); //I attempted 'put' but encountered an error
      };

 $scope.create = function( application ){
        $scope.addStatus('Under review');
 }

This is what my application JSON looks like:

{"type":"Not completed","source":"mail","number":"123-23-4231","amount":"234.44","name":"John ","id":"123","by_phone":true}

The goal is to add/append a status to the above JSON so it resembles this after adding the status property:

{"type":"Not completed","source":"mail","number":"123-23-4231","amount":"234.44","name":"John ","id":"123","by_phone":true, "status": "under review"}

The function .push() is specifically designed for manipulating JavaScript Arrays.

However, when dealing with objects that are not arrays, such as the application object in this case, a different approach is necessary. Here, instead of using .push(), we can simply assign a value directly to a property:

// rather than using push
// $scope.application.push({ 'status': text });
// we can use this simpler method
$scope.application.status = text;

When it comes to arrays, Array.prototype.push is the way to go. You can add a property in one of these two ways:

$scope.application['status'] = text;

Alternatively:

$scope.application.status = text;
