An alternative to useState.

useReducer is usually preferable to useState when you have complex state logic that involves multiple sub-values. It also lets you optimize performance for components that trigger deep updates because you can pass dispatch down instead of callbacks.

Parameters

reducer: Reducer<S, A>

Given the current state and an action, returns the new state

initialState: S

The initial value to store as state
