What are the best practices for using immutable languages?

What are the best practices for using immutable languages?

When using immutable languages, it's essential to focus on data structure design, avoid side effects, and leverage functional programming principles.

Can you give me examples of immutable data structures?

Sure! Common immutable data structures include persistent lists, sets, and maps, which allow you to create new versions without modifying the original.

How do I handle state management in an immutable language?

State management can be handled by creating new states based on previous ones, using techniques like event sourcing or functional updates.

What are the performance implications of using immutability?

Immutability can lead to increased memory usage due to the creation of new objects, but it often simplifies reasoning about code and can improve performance in concurrent environments.

Are there any libraries that help with immutability?

Yes, libraries like Immutable.js, Immer, and Ramda provide tools and utilities to work effectively with immutable data in JavaScript.
