Example from the documentation: XOR constantly changes output readings upon restart

``` javascript
const brain = require('brain.js');
// provide optional config object, defaults shown.
const config = {
inputSize: 20,
inputRange: 20,
hiddenLayers: [20, 20],
outputSize: 20,
learningRate: 0.01,
decayRate: 0.999,
};
// create a simple recurrent neural network
const inet = new brain.recurrent.RNN(config);
inet.train([
{ input: [0, 0], output: [0] },
{ input: [0, 1], output: [1] },
{ input: [1, 0], output: [1] },
{ input: [1, 1], output: [0] },
], config);
console.log(inet.run([0, 0])); // [0]
console.log(inet.run([0, 1])); // [1]
console.log(inet.run([1, 0])); // [1]
console.log(inet.run([1, 1])); // [0]
```
- output:
```
1
1
1
1
```

On Restart
output:

```

## Other Comments

I have lost all trust in this library!
Maybe I am doing something wrong?

I am currently looking for a similar library to work with nodeJS
