Here's our take.

Persistent Data Structures

Nice Pick

Developers should learn persistent data structures when building applications that need immutable state management, such as in functional programming languages (e

Pros

• g
• Related to: functional-programming, immutability

Cons

• Specific tradeoffs depend on your use case

Copy On Write

Developers should learn and use Copy On Write when implementing systems that require efficient memory management, concurrency, or data sharing, such as in operating systems (e

Pros

• g
• Related to: memory-management, concurrency

Cons

• Specific tradeoffs depend on your use case

The Verdict

Use Persistent Data Structures if: You want g and can live with specific tradeoffs depend on your use case.

Use Copy On Write if: You prioritize g over what Persistent Data Structures offers.

The Bottom Line

Persistent Data Structures wins

Developers should learn persistent data structures when building applications that need immutable state management, such as in functional programming languages (e
