Test a custom input to verify an edge case (e.g. empty lists, negative numbers, duplicates).
This bug belongs to the type errors pattern
Totals that concatenate, sorts that put 10 before 9, comparisons that refuse to run.
What went wrong: sort() with nothing inside the brackets sorts as text. As text, "100" comes before "9", because "1" comes before "9".
The fix: return nums.sort((a, b) => a - b);
Remember: to sort numbers in JavaScript, always pass (a, b) => a - b.
The pattern behind it: type errors.
