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

You can do the following:

$scope.traveler.map(o=>o.Amount).reduce((a,c)=>a+c);
