When should I use immutable data structures?

What are immutable data structures and when should I use them?

Immutable data structures are data types that cannot be modified after they are created. You should use them when you need to ensure data integrity, avoid side effects, or when working in a concurrent environment.

Can you give me an example of an immutable data structure?

Sure! A common example is a string in many programming languages. Once a string is created, it cannot be changed. If you want to modify it, a new string is created instead.

What are the benefits of using immutable structures?

The benefits include easier debugging, improved performance in certain scenarios, and safer concurrent programming since immutable objects can be shared without risk of modification.

Are there any downsides to using immutable data structures?

Yes, the main downside is that they can lead to increased memory usage and potential performance overhead due to the creation of new objects instead of modifying existing ones.
