What are the benefits of using immutable data structures?

Immutable data structures offer several benefits, including easier reasoning about code, improved performance in concurrent environments, and reduced chances of bugs due to unintended side effects.

How do immutable data structures affect performance?

They can enhance performance by enabling optimizations like structural sharing, which allows for efficient memory usage and faster comparisons.

Can you give an example of an immutable data structure?

Sure! A common example is a persistent list, where any modification creates a new version of the list while keeping the old one intact.

Are there any downsides to using immutable data?

Yes, one downside is that they can lead to increased memory usage since new copies of data are created for modifications.

When should I use immutable data structures?

You should consider using them in scenarios where data integrity is crucial, such as in functional programming or when working with concurrent systems.
