+ * 2535. Difference Between Element Sum and Digit Sum of an Array
+ * https://leetcode.com/problems/difference-between-element-sum-and-digit-sum-of-an-array/
+ * Difficulty: Easy
+ *
+ * You are given a positive integer array nums:
+ * - The element sum is the sum of all the elements in nums.
+ * - The digit sum is the sum of all the digits (not necessarily distinct)
+ *   that appear in nums.
+ *
+ * Return the absolute difference between the element sum and digit sum of nums.
+ * Note that the absolute difference between two integers x and y is defined
+ * as |x - y|.
+ */

+/**
+ * @param {number[]} nums
+ * @return {number}

+var differenceOfSum = function(nums) {
+  const sum = input => input.reduce((sum, n) => sum + +n, 0);
+  return Math.abs(sum(nums) - sum(nums.join('').split('')));
