  <pre><code>var ChildClass = class Child {
  
    howDoICallThis () {
      console.log('Called!')
    }
  
    render () {
      return (&lt;Text&gt; Child Class &lt;/Text&gt;)
    }
  }
  
  var ParentClass = class Parent {
    // how can i call child.howDoICallThis() ?
    render () {
      return (&lt;ChildClass&gt; &lt;/ChildClass&gt;)
    }
  }
