Review Summary

The implementation is missing a critical validation step explicitly required by the task description. The task states: "Make sure that the given string can be converted to a number and convert it." The code currently parses population values using replaceAll and unary + without any validation, which creates a risk if the HTML data is malformed. You need to add validation (using isNaN() or similar) before converting strings to numbers to ensure only valid numeric values are processed. Additionally, there's an inconsistent locale issue: the total uses 'en-US' but the average uses 'eu-US'. For consistent US-style population data formatting, both should use 'en-US'. Once you add the input validation as specified in the task requirements and fix the locale inconsistency, the implementation should meet all checklist items.

Review Summary

Your solution is approved. The implementation successfully meets all requirements: it correctly parses population data from span elements with class 'population', validates numeric conversion by filtering out NaN values, calculates both total and average values with proper rounding, and formats output using thousands separators with consistent 'en-US' locale. The code properly updates the 'Calculate it!' text elements as specified. All checklist criteria pass, and the previous review's concerns about validation and locale consistency have been resolved. Great work!
