Redux store object has a `dispatch` method which can be used for dispatching actions. 

When we want something to happen, for example, the counter value to be incremented, we can dispatch the `counter/increment` action using the `dispatch` method:

```js
import { configureStore } from '@reduxjs/toolkit'
const store = configureStore({ reducer: counterReducer });

// The action object can be directly created inside the method call
store.dispatch({ type: 'counter/increment', amount: 7 });

// Or it can be passed using a reference
let incrementAction = {
  type: 'counter/increment',
  amount: 7
};

store.dispatch(incrementAction);
```

The reducer function will handle this dispatched action we passed into the Redux store, `counterReducer`. The reducer function returns a new state object and updates the store accordingly – we don't have to do anything related to that; it is handled by Redux and happens on the backend, we dispatch the action using the store's method.

In this section we will learn what Redux is, why it is useful, and most importantly when it is useful. We will also learn how to set up a basic react-redux application.

In this section we will go through the fundamental concepts of Redux that are necessary to understand the workings of a Redux application. We will use code examples to understand the concepts and in the following section we will use them practically.

In the previous section we looked at the basic concepts. In this section we use those basic concepts to understand some more complicated concepts and the structure of a Redux application. In the end we will also look at the Counter application to put together all the pieces of our knowledge together.

This chapter is focused on practice hence we will utilize the knowledge we acquired in previous sections to create a practical application using Redux along with React.
