    From what I understood, the only thing that seems to be missing is the starting number:

    function count(num1, num2)                                      
{        
  let result = ""; // Always initialise in function to ensure it always sends the current result only.                                       
  let i = num1;
  for (i = num1; i <= num2; i++) // Set i = num1 instead of num+1
  {        
    result += i;
    if (i < num2) { result += ","; }                      
  }
  return result;                                     
}

    You can greatly simplify the code by incrementing the number in a loop and pushing the resulting number into an array. Once all of the numbers are in the array, you can use the Array.prototype.toString method to convert the array into a comma-separated string:

    Source

    const count = (start, end) => {
  if (start > end) return "";
  let out = [];
  let idx = start - 1;
  while (++idx <= end) out.push(idx);
  return out.toString();
};

exports.count = count;

    Tests

    const { strict: assert } = require('node:assert');
const { count } = require('./index');

assert.equal(count(0, 10), "0,1,2,3,4,5,6,7,8,9,10");
assert.equal(count(2, 5), "2,3,4,5");
assert.equal(count(5, 2), "");

    You could iterate with start and iterate until end is found.

    function count(start, end) {
    let result = start.toString();
    while (start++ < end) result += ',' + start;
    return result;
}

console.log(count(3, 3));
console.log(count(3, 7));
