4-6 - Q25 Count String

Count Strings in Objects
Complete the function stringCount that will count all string values inside an object.  The object will be filled with all kinds of data, including arrays and other objects.  Your function must find all strings, which may be deeply nested.
 
Input Format:
The function will have one argument
obj - an object, which may contain all kinds of data.
 
Output Format:
The function will return a number, representing the number of strings in the object.
 
Sample Input 1:
{
  "first": "1",
  "second": "2",
  "third": false,
  "fourth": [
    "anytime",
    2,
    3,
    4
  ],
  "fifth": null
}
 
Sample Output 1:
3 
 
Explanation:  The three strings are "1", "2", and "anytime".
 
Sample Input 2:
{
  "a": [1, 2, "3", 4],
  "b": {
    "one": [true, false, "maybe"],
    "two": {},
    "three": [[[[[[""]]]]]]
  },
  "c": [
    {
      "d": [
        {
          "e": null,
          "f": "ok"
        }
      ]
    }
  ]
}
 
Sample Output 2:
4
 
Explanation:  The four strings are "3", "maybe", "", and "ok".  (Note that the empty string is included in the count.)
