Axios gets undefined

I have React component FetchQoute which is supposed to get response from the provided URL, but it shows undefined instead ? 

class FetchQuote extends Component {
  constructor(props) {
    super(props);    
    this.state = {
      jokes: []
    };    
  }

  componentDidMount() {
    console.log(res.value); //undefined
    axios.get('https://api.icndb.com/jokes/random')
      .then((res) => {       
        this.setState({data:res.value.joke});//error TypeError: Cannot read property 'joke' of undefined
      })

  }

}

That URL can be easily tested in browser to return JSON data correctly, including res.value.joke

What's the JSON response look like in the browser? axios returns response data under the data attribute.

For example if your JSON response looks like:

{ "value": 
    { "joke": "lol"} 
}

Then you would access it like

axios.get('https://api.icndb.com/jokes/random')
      .then((response) => {       
        console.log(response.data.value.joke);
      })
