Previous State

πŸ‘¨β€πŸ’Ό We want to change things a bit to have this API:
const [count, changeCount] = useReducer(countReducer, initialCount)
const increment = () => changeCount(step)
const decrement = () => changeCount(-step)
How would you need to change your reducer to make this work?
πŸ¦‰ This step is just to show that you can pass anything as the action.
