Redux Ecosystem
A reducer stores `createdAt: new Date()` directly in state. What's the concrete problem with this, beyond 'style'?

Date objects are too large to store

Date instances aren't plain serializable data — this breaks Redux DevTools' ability to log/replay state and any persistence layer trying to serialize state to storage
C
There's no actual problem, this is fine
D
Date objects cause memory leaks
