updatePrediction() {
const result = '2';
const location = 'home';
let prediction = { home: 0, away: 0, }
if(location === 'away'){
	prediction.away = result;
} else {
	prediction.home = result;
};
this.setState({ prediction });
}

  render() {
    return (
    <div><div>Hello {this.state.prediction.home},hello {this.state.prediction.away}</div>
    <button onClick={this.updatePrediction}>
    save
    </button></div>

ReactDOM.render(
