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 give me an example of when to use immutable data structures?

Sure! Immutable data structures are great for functional programming and when you need to ensure data integrity.

What about memory usage? Is there a difference?

Yes, immutable structures can use more memory because they create new copies for changes, while mutable structures modify in place.

How does this impact performance in large applications?

In large applications, using immutable structures can lead to better performance in concurrent environments, but may increase memory overhead.

Are there any libraries that help with immutable data structures?

Yes, libraries like Immutable.js and Immer provide tools to work with immutable data structures efficiently.
