Dispatching actions

Now, there is only one thing left to do—dispatching actions to the store. You can simply pass action objects to the store.dispatch() function:

store.dispatch({ type: 'CREATE_POST', user: 'dan', text: 'hello world' })

However, it is best practice to use action creators instead, as follows:

store.dispatch(createPost('dan', 'hello world'))

Dispatching an action will result in the state being changed (by executing the reducer), and thus, the subscribed function being called:

We can now dispatch any actions we want, have the state change accordingly, and then get notified about the new state.
