Review Summary
Your solution correctly implements all the required functionality for the population calculation task. The code properly parses population data from DOM elements, calculates total and average values, and formats them with thousands separators. All [CHECKLIST ITEMS] are satisfied. The edge case with zero values in separateThousandsByComma is noted but doesn't affect the core functionality, since population data typically won't contain zero values. This is a minor consideration rather than a blocker. Your implementation is approved and meets the task requirements.

The function returns an empty string when number is 0, since the while loop condition tempNumber > 0 fails immediately. Consider adding a check for this edge case, e.g., if (number === 0) return '0';
