What are the best immutable types for performance in programming?

What are the best immutable types for performance in programming?

The best immutable types often include strings, tuples, and frozensets in Python, as they provide efficiency and safety.

Why are immutable types better for performance?

Immutable types can lead to optimizations like caching and reduced memory usage, as they cannot be changed after creation.

Can you give examples of when to use immutable types?

Sure! Use immutable types when you need to ensure data integrity, like in multi-threaded applications or when using keys in dictionaries.

Are there any downsides to using immutable types?

Yes, the main downside is that they can lead to increased memory usage if many copies are created, as they cannot be modified.
