i dont understand this js function

good day guys, i google this function and asked gpt but still i dont understand. can someone explain to me?

function array_max_consecutive_sum(nums, k) {
  let result = 0;
  let temp_sum = 0;
  for (var i = 0; i < k - 1; i++) {
    temp_sum += nums[i];
  }
  for (var i = k - 1; i < nums.length; i++) {
    temp_sum += nums[i];
    if (temp_sum > result) {
      result = temp_sum;
    }
    temp_sum -= nums[i - k + 1];
  }
  return result;
}

function array_max_consecutive_sum(nums, k) {
  let result = 0;
  let temp_sum = 0;
  for (var i = 0; i < k - 1; i++) {
    temp_sum += nums[i];
  }
  for (var i = k - 1; i < nums.length; i++) {
    temp_sum += nums[i];
    if (temp_sum > result) {
      result = temp_sum;
    }
    temp_sum -= nums[i - k + 1];

where did you get this code? It feels a little like a homework assignment to figure out what it does because that's not terribly useful

I did not find it any where this code is simply add the whole array and returning the result I do not recommend to use that, you can write more efficient code using es6
