why do we need an extra data?

Question

I noticed that when requested data with fetch we only wrote data after responseData once only

componentDidMount() {
    //start fetching data from gifs api using FETCH METHOD
    fetch('http://api.giphy.com/v1/gifs/trending?api_key=dc6zaTOxFJmzC')
      .then(response => response.json()) //this function takes the response from fetch and turns it to json format
      .then(responseData => { //make JSON data available to app by setting state
        this.setState({
          gifs: responseData.data }); //to access data in array use .data
      })
      .catch(error => { //use catch method to handle errors
        console.log('Error fetching and parsing data', error);
      });  
  }

but when we used axios to request data we had to write response.data.data

componentDidMount() {
    axios.get('http://api.giphy.com/v1/gifs/trending?api_key=dc6zaTOxFJmzC') 
    .then(response => { 
      this.setState({
        gifs: response.data.data
      });
    }) 
    .catch(error => { 
      console.log('Error fetching and parsing data', error);
   });  
  }

could someone please tell me why we wrote data.data in axios but not in fetch???

Hello, thats because axios returns an object itselfs contaning many properties, one of them is called "data" which is an object that contains the response from the giphy API which also have an array property called "data"
