Remove item from object

I'm really struggling removing an item from my object. The object has randomly generated keys so it makes it a little harder, but I can't remove the item from the object using splice... and I'm not sure why..

This is my object: $scope.todos.trackers

This is what $scope.todos looks like:

enter image description here

And this is what the trackers part of the object looks like:

enter image description here

So in order to try and delete one of the items in the tracker object (for instance the last item `note: "finally", value: 200), this is what my code looks like:

function removeIndividualTracker(uid, item) {
    angular.forEach($scope.todos.trackers, function(key, value) {
        angular.forEach(key, function(el, val) {
            console.log(key)
            console.log(item)
            if(key == item) {
                console.log($scope.todos)
                console.log($scope.todos.trackers)
                $scope.todos.trackers.splice($scope.todos.trackers.indexOf($scope.todos.trackers[value]), 1);
            }
        });
    });
}

but it doesn't work. I get an error of $scope.todos.trackers.indexOf is not a function.

Any ideas? I really don't know what to do.. Thanks!

You are getting this error because tracker is an object.You could have used indexOf if tracker was an array of objects.You can read more about it from here : MDN indexOf

Now coming back to your question, you can delete by :

function removeIndividualTracker(key) {
   delete $scope.todos.trackers[key];             
}

You can read more about delete from here: MDN delete

You are getting that error because tracker is not an Array but rather an Object. Try something like this...

function removeIndividualTracker(key) {
     delete $scope.todos.trackers[key];             
}
