// my answer to step three in code academy module on recursion in JavaScript


var stack = [];

function countDown(int) {
  stack.push(int);
  if (int === 1) {	
    return 1;
  }
    return countDown(int - 1);
}

function multiplyEach() {
  // Remove the last value of the stack 
  // and assign it to the variable int
  int = stack.pop();
  x = stack.length;
  // Base case
  if (x === 0) {
    return 1;
  }
  // Recursive case
  else {
	stack[x - 1] = int * stack[x - 1].multiplyEach();
	return stack[x - 1];
  }
}

// Call the function countDown(7)
countDown(7);
// And then print out the value returned by multiplyEach()
console.log(multiplyEach());

// when i try this, i get error back from console: "TypeError: Object 2 has no method 'multiplyEach'"
// i have no idea what i'm doing wrong here.  :(((
