Enhance the functionality of the 'validate as true' function

I have an object that resembles the following

$scope.object = {
  Title: 'A title',
  Status: 'Open',
  Responsible: 'John Doe',
  Author: 'Jane Doe',
  Description: 'lorem ipsum dolor sit'
}

My aim now is to verify if the current user has authorization to modify this item. In order for the user to be able to edit, certain conditions must be met:

  • The object must exist (not null or undefined)
  • The Responsible field must match $scope.currentUser
  • The Status field must be 'Open'

If all of these conditions are true, our function should return true. I am approaching it in the following manner

$scope.isTrue = function(){

  if($scope.object && $scope.object.Status == 'Open' && $scope.object.Responsible == $scope.currentUser){
    return true;
  } else { 
    return false; 
  }

}

It's quite simple, but is there a more efficient way to perform these checks?

Answer №1

Simply return the result of the if statement, which is either true or false.

return ($scope.item && $scope.item.Status == 'Closed' && $scope.item.Responsible == $scope.currentUser);

Answer №2

  1. Converting the outcome into a Boolean value (Therefore, if $scope.object is undefined, the result will be false instead of undefined)
  2. Utilizing strict equality operator ===
  3. Simply declaring a function and assigning it to scope (personal preference)
$scope.isTrue = isTrue;

function isTrue() {
  return Boolean($scope.object && $scope.object.Status === 'Open' && $scope.object.Responsible === $scope.currentUser);
}
