What are some examples of immutable libraries in different programming languages?

There are several programming languages that offer immutable libraries. For instance, in Java, you can use the Guava library, which provides immutable collections. In Scala, the standard library includes immutable collections by default. In JavaScript, libraries like Immutable.js and Immer are popular for handling immutability.

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 enhances performance in concurrent programming by avoiding issues related to shared state.

Are there any performance drawbacks to using immutable libraries?

Yes, there can be performance drawbacks, such as increased memory usage and potential overhead from creating new instances instead of modifying existing ones. However, many libraries optimize these operations to mitigate performance issues.

Which language do you think has the best support for immutability?

Languages like Scala and Haskell are often praised for their strong support for immutability, as they encourage functional programming paradigms. However, languages like JavaScript and Python are also improving their support through various libraries.
