Review Summary
Great work on implementing the core logic to calculate the total and average population! The code works correctly for the current data.
However, I am requesting changes because one key requirement hasn't been fully met: ensuring the string can be converted to a number before the conversion. Your current implementation doesn't validate the input. If a span contained non-numeric text, Number() would produce NaN, causing the total and average to display incorrectly as NaN.
To fix this, please add logic to handle cases where the text content is not a valid number. A good approach would be to filter out any non-numeric values before you calculate the sum. This will make your solution more robust and fully meet the task's requirements.

The code works correctly for the given HTML, but it doesn't fully meet the requirement: "Make sure that the given string can be converted to a number". If one of the span elements contained non-numeric text, Number() would produce NaN, which would then make the total and average NaN. You should add a check to handle cases where the text content cannot be converted to a valid number, for example by filtering out invalid values.

Review Summary
Excellent work on this task! I am approving your solution as it successfully meets all the requirements. You've done a great job implementing the logic for parsing, calculating, and formatting the population data. I'm particularly impressed with how you addressed the feedback from the last review by adding robust validation using .filter() and Number.isFinite(). This has made your code much more reliable. Keep up the great work!
