How to find sum of numbers in string stored in array

Question

I have figured out how to calculate the value of numbers from a single string, using as an example..

var sum = \"13-2-10-7-3\".split(\'-\').reduce(function(x, y)         


        

Answer 1

Its not the most performant, but its simple and quick

       
var ccs = ['4916-2600-1804-0530', '4779-252888-3972', '4252-278893-7978', '4556-4242-9283-2260']

// FSFL = F*Simple For-Loop
var sum = (a, b) => a + b;
var largestSum = 0; 
var largestSumLastIdx = 0;
for (let i = 0; i < ccs.length; i++) {
   let s = ccs[i].split(/-|/).map(Number).reduce(sum, 0);
   if (s >= largestSum) {
     largestSum = s;
     largestSumLastIdx = i;
   }
}

console.log("The winner is: " + ccs[largestSumLastIdx])
