title: How can I call parent method in a child React component?
body: <p>I have a parent and child compoents and I want to call a parent method in the child component like this:</p>
  
  <pre><code>import Parent from './parent.js';
  class Child extends React.Component {
      constructor(props) {
          super(props);
          };
  
      click() {
          Parent.someMethod();
      }
  
      render() {
            &lt;div&gt;Hello Child onClick={this.click}&lt;/&gt;
      }
  }
  
  class Parent extends React.Component {
      constructor(props) {
          super(props);
          };
  
      someMethod() {
          console.log('bar');
      }
  
      render() {
            &lt;div&gt;Hello Parent&lt;/&gt;
      }
  }
  </code></pre>

  <p><code>Uncaught TypeError: _Parent2.default.someMethod is not a function</code></p>
