What is the concept of Immer in JavaScript?

Can you explain what Immer is in JavaScript?

Sure! Immer is a library that helps you work with immutable state in JavaScript. It allows you to write code that looks like you're mutating state directly, but under the hood, it creates a new immutable state.

How does Immer handle state updates?

Immer uses a concept called 'drafts'. When you create a draft of your state, you can make changes to it as if it were mutable. Once you're done, Immer produces a new immutable state based on those changes.

Can you give me an example of using Immer?

Absolutely! Here's a simple example: you can use produce from Immer to update an object. For instance, produce(state, draft => { draft.count += 1; }) will return a new state with the count incremented.

What are the benefits of using Immer?

The main benefits are improved readability and maintainability of your code, as it allows you to write simpler and more intuitive state updates without worrying about immutability.
