JavaScript Component “loop” with React JS loop component in react,loop component in talend,create react

JSON input data seems to be invalid. Validated it on JSONParser

ImageList component expects children JSON Array inside the data object. So if AJAX call returns following JSON, component would be able to render that data

{
  "children": [
    {
      "score": 4
    },
    {
      "score": 2
    }
  ]
};

Please note that this.setState({data: data}); is already having data variable. So the response should not again set data else it becomes data.data.children. That is why code is throwing Uncaught TypeError: Cannot read property 'map' of undefined.

For further reading after you complete ReactJS study, I would recommend to check Flux Architecture, which is recommended way of implementing ReactJS applications
