My challenge involves an array consisting of ten objects, each with six properties to be displayed on a view. I want users to have the ability to update these properties by entering new data into inputs. How can I efficiently monitor the entire array to identify which property within which object has been changed, without having to duplicate my code for each individual object?
If you want to monitor changes in a collection, consider utilizing $watchCollection
$scope.$watchCollection('data', function (newVal, oldVal) { /*...*/ });
It's generally not recommended to monitor large groups of objects in AngularJS because it can lead to performance issues with equality checks during digest loops. However, if you must do so, the $scope.$watch function offers the option of using the third parameter, objectEquality, where you can provide a boolean function that determines whether the old and new values are equal. Alternatively, you can simply pass true as the third parameter.
Another approach is to use
