Better way to sum a property value in an array

Question

I have something like this:

$scope.traveler = [
            {  description: \'Senior\', Amount: 50},
            {  description: \'Senior\', Amount: 50},
             


        

Answer 1

can also use Array.prototype.forEach()

let totalAmount = 0;
$scope.traveler.forEach( data => totalAmount = totalAmount + data.Amount);
return totalAmount;
