What are immutable data structures in Scala?
Immutable data structures in Scala are collections that cannot be modified after they are created. This means any operation that would modify the structure instead returns a new instance.
Can you give me an example of an immutable list in Scala?
Sure! In Scala, you can create an immutable list like this: val myList = List(1, 2, 3)
. You can't change myList
, but you can create a new list with added elements.
What are the benefits of using immutable data structures?
The benefits include easier reasoning about code, thread safety, and avoiding side effects, which can lead to fewer bugs.
How do immutable data structures affect performance?
While they can have overhead due to creating new instances, they often lead to better performance in concurrent applications due to their thread-safe nature.
