What is Immutable State?
Immutable state in Redux refers to the principle that the state within your Redux store should not be directly mutated. Instead, when you want to update the state, you create a new copy of the state with the desired changes. This ensures that the original state remains unchanged.
Benefits of Immutable state:
- Predictability: With immutable state, you can easily predict how your application’s state will change over time since it avoids unexpected mutations.
- Debugging: Immutable state makes it easier to debug your application because you can trace the changes to the state more accurately.
- Performance Optimization: Immutable updates can be optimized for performance in certain scenarios, such as in React applications with shallow equality checks.
- Time-Travel Debugging: Redux’s dev tools rely on immutability to enable features like time-travel debugging, where you can step backward and forward through the state changes.
How to handle Immutable State in Redux Reducers?
Managing immutable states in reducers is a core principle of Redux that is used for maintaining the predictability and consistency of the application’s state throughout its lifespan. Immutable state denotes that once a state object is created, it cannot undergo direct modification. If there are any alterations to the state trigger, then there will be a fresh state object created.
In this article, we will see what is immutable state and different ways to handle the immutable states.
