What are the best libraries for working with immutable data structures?

Some of the best libraries for immutable data structures include Immutable.js, Immer, and Mori. Would you like to know more about any specific one?

Can you explain how Immutable.js works?

Immutable.js provides persistent immutable data structures, meaning that when you modify a structure, it returns a new version without altering the original. This helps in maintaining state in applications.

What are the advantages of using immutable data structures?

Using immutable data structures can lead to easier debugging, better performance in certain scenarios, and safer concurrent programming since data cannot be changed unexpectedly.

Are there any performance drawbacks?

Yes, there can be performance drawbacks, especially in terms of memory usage, as new copies of data structures are created. However, libraries like Immutable.js optimize this with structural sharing.
