Review Comment:
<!-- Bito Reply -->
The discussion in the thread revolves around whether the `if (oldestKey !==
undefined)` guard should be removed from the `LRUCache` implementation. The
reviewer insists that the guard is necessary for TypeScript 6.0
forward-compatibility, as `Map.keys().next().value` is typed as `K |
undefined`, and the guard ensures type safety under strict null checks. Bito's
suggestions to remove the guard are declined because they would violate
TypeScript's type-checking rules, even if the runtime logic seems safe. The
thread is closed with the conclusion that the guard must remain for type
correctness.
