How to access the inside function

JavaScript

Tell us what’s happening:

why isn’t the inside function being called?

Your code so far


function addTogether(one, two) {
if(!Number.isInteger(one) || !Number.isInteger(two)) return undefined;
if(two) return (one+two);

function inside(num){
  if(!Number.isInteger(num)) return undefined;
  return (one+num);
}
return inside;
}

addTogether(2,3);

If two is undefined, then the first case will have executed and your addTogether function will return undefined. Otherwise it will satisfy the second condition and return one + two.
