useReducer

by Pawan Kumar @jsartisan

React provides the useReducer hook as an alternative to useState for managing complex state logic.

Your task is to implement your own version of useReducer from scratch.

Create a custom hook called useReducer that:
- Accepts a reducer function and an initialState.
- Returns the current state and a dispatch function.
- Updates the state when dispatch is called with an action.
The state update logic should follow the reducer pattern:
```
(state, action) => newState;
```
Ensure that the component re-renders whenever the state changes.
Demonstrate your custom useReducer by using it in the given simple counter component with increment, decrement, and reset actions.
