What is the impact of immutability on software design?

Immutability in software design means that once an object is created, it cannot be changed. This can lead to safer and more predictable code.

Can you explain why immutability is beneficial?

Sure! Immutability helps prevent side effects, making it easier to reason about code and reducing bugs, especially in concurrent programming.

Are there any downsides to using immutability?

Yes, while immutability offers many benefits, it can lead to increased memory usage and performance overhead due to the creation of new objects.

How does immutability affect state management in applications?

Immutability simplifies state management by ensuring that state changes are explicit and traceable, which is crucial in frameworks like Redux.

Can you give examples of programming languages that support immutability?

Languages like Haskell, Scala, and even JavaScript (with libraries like Immutable.js) support immutability, promoting safer coding practices.
