16+18=214 For this Kata you will have to forget how to add two numbers together. In simple terms, our method does not like the principle of carrying over numbers and just writes down every number it calculates :-) You may assume both integers are positive integers

  num1 = ('' + num1).split('').reverse()
  num2 = ('' + num2).split('').reverse()
  let max = Math.max(num1.length, num2.length)
  let str = [];
  for(let i = 0; i < max; i++)
    str.push((parseInt(num1[i]) || 0) + (parseInt(num2[i]) || 0))
  num1 = str.reverse().join('');
  return parseInt(num1);
