Where did I make a mistake in the code?

Question

JavaScript

orderList stores data from localStorage.
Anything starting with $scope.totalPrice doesn't work.

diskShop.controller('diskBasketCtrl', function($scope) {
    $scope.baskets = orderList;
    $scope.totalPrice = function($scope) {
        var total = 0;
        angular.forEach($scope.baskets, function(baskets) {
            total += baskets.Price;
        });
        return total;
    }
});

Answer 1

Why indulge in $scope in the totalPrice parameters if it is already visible?
