What are the benefits of using immutable collections in programming?

Immutable collections offer several benefits, such as improved performance, easier debugging, and enhanced thread safety.

Can you explain how they improve performance?

Sure! Immutable collections can lead to performance gains because they avoid the overhead of copying data when changes are made, allowing for more efficient memory usage.

What about thread safety? How does that work?

Since immutable collections cannot be changed after creation, they are inherently thread-safe. Multiple threads can access them without the risk of data corruption.

Are there any downsides to using immutable collections?

Yes, one downside is that they can lead to increased memory usage if many versions of a collection are created. However, the benefits often outweigh this.

Can you give me an example of an immutable collection in a programming language?

Certainly! In Java, the List.of() method creates an immutable list. In Python, you can use tuples as immutable sequences.
