What are the differences between Immutable.js and normal arrays?

Immutable.js provides persistent data structures that are immutable, meaning they cannot be changed after creation, while normal arrays in JavaScript are mutable.

Why would I choose Immutable.js over regular arrays?

Choosing Immutable.js can lead to better performance in certain scenarios, especially in applications with complex state management, as it helps avoid unintended side effects.

Are there any downsides to using Immutable.js?

Yes, there can be a learning curve, and it may introduce additional overhead in terms of performance for simple use cases compared to regular arrays.

Can you give an example of how to use Immutable.js?

Sure! You can create an Immutable List like this: import { List } from 'immutable'; const myList = List([1, 2, 3]); This list is immutable, so any modifications will return a new list.
