Is it possible to display the sum of the elements of two arrays in one action?

Question

JavaScript

function sumTwoArrays(arr1, arr2) {
  let sum1 = arr1.reduce((sum, cur) => sum + cur);
  let sum2 = arr2.reduce((sum, cur) => sum + cur);
  return sum1 + sum2;
}

Answer 1

it is possible, if there are 2 elements in the sum of two arrays, then the action will be one. This is if we talk exclusively about mathematical operations.
If you want to write all this in one line, you can do concat and only then reduce
