counter with redux
const INCREMENT = "INCREMENT"; // define a constant for increment action types
const DECREMENT = "DECREMENT"; // define a constant for decrement action types
// define the counter reducer which will increment or decrement the state based on the action it receives
const counterReducer = (state = 0, action) => {
switch (action.type) {
case INCREMENT:
return state + 1;
case DECREMENT:
return state - 1;
default:

}
};
// define an action creator for incrementing
const incAction = () => {
return {
type: INCREMENT
};
};
// define an action creator for decrementing
const decAction = () => {
return {
type: DECREMENT
};
};
// define the Redux store here, passing in your reducers
const store = Redux.createStore(counterReducer);
