    // Note: The StringAt method returns the value as a string regardless of the type.
    // If the value is a JSON array (such as for ["home", "green"]), then the JSON encoding
    // of the entire array is returned.

    // The IntAt method returns the value as an integer.  If the value does not convert to 
    // an integer, then 0 is returned
