What are some libraries for handling immutable data in JavaScript?

There are several libraries for managing immutable data in JavaScript, such as 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 Immer?

Immer allows you to work with mutable code while it handles the immutability under the hood. This makes it easier to write and understand your code, especially in state management.

Are there any performance considerations with these libraries?

Yes, while these libraries can improve performance in certain scenarios by reducing unnecessary re-renders, they can also introduce overhead. It's essential to evaluate based on your application's needs.
