Episode notes
Immutability Not Essential
- Immutability, while helpful for functional programming, isn't strictly required.
- Functional thinking can still apply to mutable situations.
Mutable Reads as Actions
- Reading from mutable data structures is an action, not a calculation.
- Functional programming prefers calculations using immutable data.
Practical Immutability
- Achieve practical immutability through discipline, not just language features.
- If no code modifies data, it's effectively immutable, regardless of flags or setters.
