What are the performance differences between immutable libraries?

Immutable libraries, like Immutable.js and Immer, have different performance characteristics. Immutable.js uses structural sharing, which can be faster for certain operations, while Immer allows for a more straightforward syntax but may have overhead due to its proxy-based approach.

Can you give examples of when to use each library?

Sure! Use Immutable.js when you need high performance with large datasets and complex state management. Immer is great for simpler state updates where readability and ease of use are priorities.

What about memory usage? Is one more efficient than the other?

Generally, Immutable.js can be more memory efficient due to its structural sharing, but it can also lead to higher memory usage in some cases. Immer may use more memory during updates because of its proxy mechanism.

Are there any benchmarks available for these libraries?

Yes, there are several benchmarks available online that compare the performance of these libraries in various scenarios. It's best to check the latest ones as performance can vary based on the specific use case.
