What is the performance impact of mutability in programming?

Mutability refers to the ability of an object to be changed after it is created. In programming, mutable objects can lead to performance issues, especially in concurrent environments.

Can you give me an example of mutable vs immutable objects?

Sure! In Python, a list is mutable, meaning you can change its contents. A tuple, on the other hand, is immutable; once created, its contents cannot be altered.

How does mutability affect memory usage?

Mutable objects can lead to higher memory usage because they may require additional memory for changes. Immutable objects, however, can be more memory-efficient as they can be shared across different parts of a program.

Are there any performance benefits to using immutable objects?

Yes, immutable objects can improve performance in certain scenarios, such as when used in functional programming or when thread safety is a concern, as they eliminate the need for locks.
