Managing state is a hard problem when it comes to Angular. There is a need to coordinate multiple backends, web workers, and UI components, all of which update the state concurrently. Patterns like Redux make some of this coordination explicit. It is the most popular state management library for React apps
React boosts developers’ productivity. It helps write clean and modular code, it breaks the code into separate components, and allows code reuse. Learning it will help you understand the patterns that have been popularized by it in Web development.
Redux can be used for any UI layer but it is most useful when combined with a declarative view implementation that can infer the UI updates from the state changes, such as React. Hence, Redux with React has become one of the most popular combinations.
Several popular companies like Instagram, Robinhood, Stack and Revolut. use Redux.
