What is immutable data in Angular and why is it important?

Immutable data in Angular refers to data that cannot be changed after it is created. This is important because it helps in maintaining state consistency and makes it easier to track changes, which is crucial for performance and debugging.

Can you give me an example of how to implement immutable data in an Angular application?

Sure! You can use libraries like Immutable.js or the spread operator in ES6 to create immutable data structures. For example, instead of modifying an array directly, you can create a new array with the updated values.

What are the benefits of using immutable data in state management?

Using immutable data in state management can lead to easier debugging, improved performance through change detection, and a more predictable application state.

Are there any downsides to using immutable data?

Yes, one downside is that it can lead to increased memory usage since new copies of data are created instead of modifying existing data. It may also require a learning curve for developers unfamiliar with the concept.
