Factorialize a Number _Maximum call stack size exceeded

Tell us what’s happening:

Need help bro:
Why the first function will result in “Maximum call stack size exceeded”

Your code so far





function factorialize(num) {
  if(num == 0){return 1;}
  return num*factorialize(num--);
}

function factorialize(num) {
  if (num === 0) { return 1; }
  return num * factorialize(num-1);
}

The location of the decrement operator matters. num-- does not return the same thing as --num

factorialize(5)
num is 5
return 5 * factorialize(5)
  num is 5
  return 5 * factorialize(5)
    num is 5
    return 5 * factorialize(5)
      and so on
