What exactly is Redux used for?

The video introduces the concept of Redux in a concise and engaging manner, aiming to encapsulate its essence in just 100 seconds. It highlights a key function of Redux that plays a pivotal role in the framework's architecture.

This function, at the heart of Redux, returns a new object, which encapsulates the entire application state. By maintaining a single source of truth for the application's state, Redux simplifies state management significantly.

The end result of this approach is a one-way data Flow that is inherently predictable. The unidirectional flow ensures that changes to the state can be traced back to their origins, making debugging and troubleshooting much more straightforward.

Furthermore, the predictability of this data flow also makes the application more testable. Automated tests can be written with confidence, knowing that the state changes will always follow the same predictable path.

Beyond its practical benefits, Redux's architecture also fosters the development of powerful developer tools. These tools leverage the predictability and testability of the framework to provide insights and functionalities that enhance the overall development experience.
