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: === on two arrays is only true if they are the same array. Two separate arrays are never ===.
The fix: return a.length === b.length && a.every((x, i) => x === b[i]);
Remember: to compare array contents, compare item by item.
The pattern behind it: type errors.
