How does useReducer differ from useState?
useState | useReducer |
---|---|
Handles state with a single value | Handles state with more complex logic and multiple values |
Simple to use, suitable for basic state needs | More complex, suitable for managing complex state logic |
Simple state updates, like toggles or counters | Managing state with complex transitions and logic |
Directly updates state with a new value | Updates state based on dispatched actions and logic |
Not used | Requires a reducer function to determine state changes |
Logic is dispersed where state is used | Logic is centralized within the reducer function |
