<div id="container">

<!-- Code so erweitern, dass beim Click auf ResetButton die Zähler der beiden MyButtons zurückgesetzt werden -->

CSS

button {
  display: block;
  width: 200px;
  height: 80px;
  }

Babel + JSX

class ResetButton extends React.Component {
			handleClick(e){
      	// ?
      }
			render(){
      	return <button onClick={this.handleClick} >Reset</button>;
      }
};

class MyButton extends React.Component {
			 constructor(props) {
        super(props);
        this.state = { count:0 };
      }
      handleClick(e){
      	this.setState({ count:this.state.count +1 });
      }
			render(){
      	return <button onClick={this.handleClick.bind(this)} >{this.state.count}</button>;
      }
};

ReactDOM.render(
  (
  	<div>
      <ResetButton />
      <MyButton />
      <MyButton />
    </div>
  ),
  document.getElementById('container')
);
