How does Immutable.js work?

Can you explain how Immutable.js works?

Sure! Immutable.js is a library that provides immutable data structures for JavaScript, which means once you create a data structure, it cannot be changed.

What are the benefits of using immutable data structures?

Using immutable data structures can help prevent unintended side effects, make your code easier to reason about, and improve performance in certain scenarios by enabling structural sharing.

How does it handle updates to data?

Immutable.js uses persistent data structures, which means that when you update data, it creates a new version of the data structure while keeping the old one intact, allowing for efficient updates.

Can you give an example of how to use it in a React application?

Absolutely! In a React app, you can use Immutable.js to manage your state. For example, you can create an Immutable List and update it using methods like push or setIn, which return a new List without mutating the original.
