Redux

Redux is a predictable state container for JavaScript apps, often used with React but also usable with other frameworks or vanilla JavaScript. It is based on the Flux architecture and enforces a unidirectional data flow, which makes state mutations predictable.

How Redux Works:

• Single Source of Truth: Redux uses a single store that holds the entire state of your application. This makes it easier to track changes over time and debug or inspect the application.

• State is Read-Only: The only way to change the state is to dispatch an action, which is a plain JavaScript object describing what happened. This ensures that neither the views nor the network callbacks will ever write directly to the state.

• Changes are Made with Pure Functions: To specify how the state tree is transformed by actions, you write pure reducers. A reducer is a pure function that takes the previous state and an action and returns the next state.

Services Provided by Redux:

• Centralized State Management: Redux provides a central place to store and manage all application state, making it easier to keep different parts of the UI in sync.

• DevTools: Redux offers powerful development tools for time-travel debugging, state inspection, and hot reloading of reducers.

• Middleware: Redux allows the use of middleware for logging, crash reporting, asynchronous API handling, and more.
