Subtract the Product and Sum of Digits of an Integer

var subtractProductAndSum = function(n) {
 let num = n.toString().split("");
   let count = num.reduce((acc, sum)=>{
    acc += Number(sum);
       return acc;
}, 0);
   let mul = num.reduce((acc, sum)=>{
   acc *= Number(sum);
        return acc;
}, 1);
    
  return mul - count;
};

Given an integer number n, return the difference between the product of its digits and the sum of its digits.

Example 1:

Input: n = 234
Output: 15
Explanation:
Product of digits = 2 * 3 * 4 = 24
Sum of digits = 2 + 3 + 4 = 9
Result = 24 - 9 = 15
