What are some real-world examples of immutable data structures?

What are some real-world examples of immutable data structures?

Immutable data structures are those that cannot be modified after creation. Examples include strings in Python, tuples, and certain data structures in functional programming languages like Haskell.

Can you explain why immutability is important?

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

Are there any performance benefits to using immutable data structures?

Yes, immutable data structures can lead to performance benefits in certain scenarios, such as enabling optimizations like structural sharing, which reduces memory usage.

What programming languages support immutable data structures?

Many programming languages support immutable data structures, including JavaScript, Scala, Clojure, and Python, among others.

Can you give an example of an immutable data structure in JavaScript?

In JavaScript, you can use the Object.freeze() method to create an immutable object. Once frozen, the object cannot be modified.
