What is Normalization in Redux?

Normalization in Redux refers to organizing and structuring your application’s state in a way that eliminates redundancy and ensures data consistency. It involves storing data in a format similar to how a relational database organizes tables, where related entities are separated into distinct collections and linked by unique identifiers (IDs).

Why Normalize State in Redux?

1. Avoid Redundancy: Keeps state efficient by eliminating duplicated data.
2. Consistency: Ensures that updates to an entity are reflected wherever it is referenced in the state.
3. Improved Performance: Simplifies updates and reduces the need to traverse or deeply copy nested structures.
4. Scalability: Makes it easier to manage and query large or complex state trees.

When is Normalization Useful?

Normalization is most beneficial when:

• You have related or nested data, such as users and their posts.
• Multiple parts of the application need to access and update shared data.
• You’re working with APIs that return deeply nested or redundant data.
