Following up from the linked issue, input data as an array of numbers seems to break the retro() function.

var net = new brain.NeuralNetwork();

      net.train([
        {input: [0, 0], output: [0]},
        {input: [0, 1], output: [1]},
        {input: [1, 0], output: [1]},
        {input: [1, 1], output: [0]}
      ]);

      var output = net.run([1, 0]);
      console.log('out', output);// [0.933]
      console.log('retro', retro(output, net));// {2: NaN}

In addition, my real world output is more like:{isIt:1}
