What is the primary role of a reducer in Redux?

  • Controlling the UI components.
  • Handling HTTP requests.
  • Managing the application's state.
  • Validating user input.
A reducer's primary role in Redux is to manage the application's state. Reducers are responsible for specifying how the application's state changes in response to actions. They take the current state and an action as input and return a new state. While other components like middleware may handle HTTP requests or UI components control the user interface, reducers are specifically designed for state management.
