Review Summary

I am approving your solution because it correctly parses all .population spans, strips commas, converts the text to numbers, and then computes both the total and the average as required. You then update the .average-population and .total-population spans with the calculated values, using toLocaleString() so the output matches the thousands separator style of the input data, which satisfies the formatting requirement [CHECKLIST ITEM #5, #6, #7]. The logic for summing and averaging is straightforward and accurate, and you’ve respected the constraint to only modify src/scripts/main.js [CHECKLIST ITEM #8, #9]. The only potential improvement would be to defensively check for NaN before adding values to the total (for example, if (!Number.isNaN(populationNumber)) { ... }) to handle any unexpected non-numeric content, but this is a robustness enhancement rather than a functional requirement. Overall, your implementation meets the core functional and checklist requirements for this file, and the behavior should work correctly for the specified task.
