Fetching data with Redux

Question

What are the advantages of fetching data with Redux as described here compared to just using the regular pattern with

class Posts extends Component {
  state = { posts: [] };

  componentDidMount() {
    fetch(url).then(res => this.setState({ posts: res.json().posts });
  }

  render() {
    return ... 
  }
}

Is it to make asynchronous fetching easier? Does it make it easier to persist the data in the store, so I can retrieve it when I reopen the app without having to fetch again?

Answer 1

It is actually not a question about why to fetch data from async actions, it seems you need to understand what advantages Redux library as a whole brings.
