What are the performance benefits of using immutable types?

Using immutable types can lead to performance improvements in several ways, such as better memory management, easier debugging, and enhanced concurrency.

Can you explain how they improve memory management?

Immutable types can reduce memory overhead because they allow for sharing of instances. When an object is immutable, it can be reused instead of creating new instances, which saves memory.

What about debugging? How does immutability help?

Immutability simplifies debugging because the state of an object cannot change after it's created. This means you can rely on the object's state being consistent throughout its lifecycle.

Are there any downsides to using immutable types?

Yes, while they offer many benefits, immutable types can lead to performance overhead in scenarios where frequent updates are necessary, as new instances must be created for each change.
