Review Summary

I am approving your solution because it correctly implements all the required functionality in main.js and aligns with the checklist items that apply to this file. You successfully collect all .population span values, strip commas, convert them to numbers, and compute both the total and the average from that list, satisfying the core calculation requirements [CHECKLIST ITEM #1, #3, #4, #13]. You then update the .total-population and .average-population spans with the computed values, formatting them via toLocaleString() so the thousands separators match the original data [CHECKLIST ITEM #5, #6, #7]. You also respected the constraints of not modifying the HTML or CSS and keeping changes contained to src/scripts/main.js [CHECKLIST ITEM #8, #9].

The only remaining points relate to project-level tasks (running the lint command, following the external guideline, and ensuring the demo link uses your actual GitHub username), which are outside this file but still important to double-check before final submission [CHECKLIST ITEM #10–#12]. As a minor, non-blocking improvement, you could make the code a bit more defensive by skipping any values that convert to NaN, in case future data is malformed. Overall, your implementation is clear, meets the functional requirements, and demonstrates solid handling of DOM querying, number parsing, and formatting—nice work.
