Majority Element LeetCode solution in JavaScript

1
var majorityElement = function (nums) {

  // Initialize sol and cnt to store the solution and its frequency for respective iterations...
3
  let sol = 0,
4
    cnt = 0;
5
  // For every element i in the array...
6
  for (let i = 0; i < nums.length; i++) {
7
    // If cnt is equal to zero, update sol as sol = i
8
    if (cnt == 0) {
9
      sol = nums[i];
10

11
    }
12
    // If i is equal to candidate, increment cnt...
13
    else if (sol == nums[i]) {
14
      cnt++;
15
    }
16
    // Otherwise, decrement cnt...
17
