Immutable.js vs Immer: Which One Should You Use?

What are the main differences between Immutable.js and Immer?

Immutable.js provides persistent immutable data structures, while Immer allows you to work with mutable state and automatically produces immutable updates.

Which one is better for performance?

It depends on your use case. Immutable.js can be faster for large data sets due to its structural sharing, while Immer is often easier to use and can be more performant for smaller updates.

Can you give an example of how to use both?

Sure! In Immutable.js, you would create an Immutable.Map and use methods like set to update it. In Immer, you would use a produce function to create a draft state and modify it directly.

What are the pros and cons of each?

Immutable.js offers performance benefits and a rich API, but has a steeper learning curve. Immer is simpler and more intuitive but may have performance overhead in some scenarios.
