What is Immer and how does it work?

Immer is a JavaScript library that helps manage immutable state in applications. It allows you to work with mutable state while keeping the benefits of immutability.

Can you explain how it handles state updates?

Sure! Immer uses a concept called 'drafts'. You can modify a draft state directly, and when you're done, Immer produces a new immutable state based on those changes.

What are the benefits of using Immer?

The main benefits include easier state management, reduced boilerplate code, and improved readability of your code.

Are there any performance concerns with using Immer?

Generally, Immer is optimized for performance, but in very large states or complex updates, you might want to profile your application to ensure it meets your needs.
