How do immutable types affect performance?

Can you explain how immutable types affect performance in programming?

Sure! Immutable types are objects whose state cannot be modified after they are created. This can lead to performance benefits, especially in multi-threaded environments, as they are inherently thread-safe.

What are some examples of immutable types?

Common examples include strings in Java and Python, and tuples in Python. These types cannot be changed once created.

Are there any downsides to using immutable types?

Yes, one downside is that they can lead to increased memory usage since a new object is created for each modification, rather than modifying the existing object.

How do immutable types compare to mutable types in terms of performance?

Immutable types can be slower for operations that require frequent changes, while mutable types are generally faster for such operations. However, immutable types can offer better performance in concurrent scenarios.
