if json is not empty

The code is checking to see if the retJson object has any key-value pairs. If it does not, the state of the app is set to {isEditing:false} and the app returns. If the retJson object does have key-value pairs, the code retrieves the first key from the Object.keys(retJson) list and sets the state of the app to {thatKey:value}; then it returns.

if (Object.keys(retJson).length == 0) {
    this.setState(
    {
    //isEditing: false
    }
    );
    return;
  }
