Recursive Multiplication

Given an JavaScript object list of books that each have a pages attribute to define the number of pages in the book, find the product of all the pages in the object list of books using recursion (you must use recursion to solve this problem).

Keep in mind:

  • The input list object may be completely empty (ex. {})
  • The next attribute may not be defined

function getPageCount(list) {
// your code here
// returns an integer
}

Example test case:
Input:
{
"book":"A",
"pages":1,
"next":{
"book":"B",
"pages":2,
"next":{
"book":"C",
"pages":3,
"next": null
}
}
}

Output: 6
Reasoning: 1 * 2 * 3 pages
