using a for loop works just fine, but this is a great use case for .map

let ints = parseInt(numbers[i], 10)
newArr.push(ints)
}
return newArr;
}
stringsToNumbs(strNums);


// With the same numbers, find the sum of the even values
const sumEvens = stringsToNumbs(strNums).filter(x => x%2==0).reduce((total, amount) => total+amount)

nice use of method chaining!
