What are some programming languages that support immutable data?

What are some programming languages that support immutable data?

Many programming languages support immutable data, including Haskell, Scala, and Clojure. These languages emphasize immutability to enhance safety and concurrency.

Can you explain why immutability is important in programming?

Immutability is important because it helps prevent side effects, making code easier to understand and maintain. It also allows for safer concurrent programming.

Are there any languages that don't support immutable data?

Yes, languages like Java and C do not enforce immutability by default, but they do provide ways to create immutable objects.

How do you implement immutability in Java?

In Java, you can implement immutability by declaring a class as final, making fields private and final, and not providing setters.

What are the performance implications of using immutable data?

Using immutable data can lead to increased memory usage due to object creation, but it can also improve performance in concurrent applications by avoiding synchronization.
