How does Immer work in depth?

Can you explain how Immer works in managing state in JavaScript applications?

Sure! Immer is a library that allows you to work with immutable state in a more convenient way. It lets you write code that appears to mutate state directly, while it actually creates a new immutable state behind the scenes.

How does it handle nested objects?

Immer uses a concept called 'drafts'. When you create a draft of your state, you can modify it as if it were mutable. Immer tracks these changes and produces a new state object that reflects the modifications, even for deeply nested structures.

What are the benefits of using Immer over traditional state management?

The main benefits include simpler syntax, reduced boilerplate code, and improved readability. It also helps prevent accidental mutations, which can lead to bugs in your application.

Can you give an example of using Immer in a React application?

Absolutely! In a React app, you can use Immer with the produce function to update state. For example, you can write produce(state, draft => { draft.count += 1; }) to increment a count value in your state.
