What are the performance differences between immutable and mutable data structures?

What are the performance differences between immutable and mutable data structures?

Immutable data structures cannot be changed after creation, while mutable ones can. This affects performance in various ways.

Can you explain how this affects memory usage?

Sure! Immutable structures often require more memory because each change creates a new version, while mutable structures modify in place.

What about speed? Are immutable structures slower?

Yes, they can be slower for certain operations since they involve creating new copies, but they can be optimized in functional programming.

Are there scenarios where immutable structures are preferred?

Absolutely! They are preferred in concurrent programming as they avoid issues with shared state, making them safer to use.
