ListView.DataSource looping data for React Native

When I do a Console.log(this.state.dataSource) I get the image as below, I'm currently getting "Row goes here!"x 4 because the API return 4 results.

I tried to retrieve the user data like email but it wont "loop" and print accordingly.

I'm not exactly sure how this code works, comments would help abit.Please Advice

    var messagesTab = React.createClass({
  componentWillMount: function() {
    fetch('https://randomuser.me/api/?results=4')
      .then(res => res.json())
      .then(res => this.updateDataSource(res));
  },
  getInitialState: function() {
    return {
      dataSource: new ListView.DataSource({
        rowHasChanged: (r1, r2) => r1 !== r2
      })
    };
  },
  updateDataSource: function(data){
    this.setState({
      dataSource: this.state.dataSource.cloneWithRows(data)
    })
  },
  renderRow: function (){
    return (
      <View>
        <Text>Row goes here!</Text>
      </View>
    );
  },
  render: function(){
    console.log(this.state.dataSource);
    return (
      <View style={ styleseact.container }>
        <ListView dataSource={ this.state.dataSource } renderRow={ this.renderRow } />
      </View>
    );
  }
});

I got this when I did a console.log(data); on renderRow

You're overwriting your DataSource declaration. Split up the declaration and update.

Declare this before React.createClass:

var ds = new ListView.DataSource({
  rowHasChanged: (r1, r2) => r1 !== r2
});

Remove it from getInitialState:

getInitialState: function() {
  return {
    dataSource: ds.cloneWithRows([])
  };
},

And reference it in the update function:

updateDataSource: function(data){
  this.setState({
    dataSource: ds.cloneWithRows(data)
  })
},
