Benefits of Immutable Data in Redux
- Predictability – Predictability means that you can easily understand how and when changes occur in your application’s state. With immutable data in Redux, every time you want to update the state, you create a new state object instead of modifying the existing one. This ensures that the state remains consistent and doesn’t change unexpectedly.
- Debugging – By eliminating the possibility of side effects (unintended consequences of modifying data), immutable data makes testing and debugging more straightforward. You can isolate specific parts of your code and test them with well-defined inputs.
- Performance – Immutable data in Redux improves performance by enabling faster change detection. Components connected to the state can efficiently determine if they need to re-render using shallow equality checks. This optimization is crucial as your app scales, handling larger state objects and complex component structures.
- Undo/Redo –Since every state change produces a new state object, implementing undo and redo functionality becomes straightforward. You can maintain a history of past states and navigate between.
What are the Benefits of using Immutable Data in Redux ?
In Redux, immutable data means that once you create the state, you can’t directly change it. Instead, whenever you need to update the state, you create a new state object. This keeps your original state safe and offers benefits like predictability, easier debugging, and performance optimizations. In this article, we make a project that implements an Undo/Redo functionality and shows the use case of an immutable state in Redux.
