Test a custom input to verify an edge case (e.g. empty lists, negative numbers, duplicates).
This bug belongs to the logic errors pattern
The wrong operator, an inverted condition, a formula the right way round but backwards.
What went wrong: "Racecar" reversed is "racecaR". Capital R and small r are different.
The fix: const w = word.toLowerCase(); return w === w.split("").reverse().join("");
Remember: lowercase text before comparing when capitals should not matter.
The pattern behind it: logic errors.
