Use enum constants instead of hardcoded values

When a value comes from a finite set, model it as an enum constant instead of string/int literals.

Why this matters

Enums provide type safety, discoverability, and avoid typos and drift.

Side-by-side examples engineers can pattern-match during review.

Avoid

if (status.equals("APPROVED")) { /* ... */ }

Prefer

enum Status { PENDING, APPROVED, REJECTED }
if (status == Status.APPROVED) { /* ... */ }

Bad

if (role.equals("admin")) {}

Good

if (role == Role.ADMIN) {}

From the same buckets as this rule.

Avoid Duplicating String Literals
Store repeated string literals in constants or variables to improve maintainability and reduce redundancy.

Avoid Empty Methods
Detect methods that have an empty body. If a method is empty, ensure that a comment is present explaining why it remains unimplemented.

Avoid modifying built-in prototypes
Detect modifications to built-in prototypes. Modifying built-in objects can lead to compatibility issues and unexpected behavior. Recommend creating helper functions instead.
