title: typescript - how to access "root" class method
body: <p>I have class inherited from other class which inherits other class, something like this:</p>
  
  <pre><code>class RootClass {
    call(): void;
  }
  
  class SubClass extends RootClass {
    call(): void:
  }
  
  class MyClass extends SubClass {
    call(): void {
      RootClass.call();  // how to access parent class's parent class?
    }
  }
  </code></pre>
  
  <p>It seems <code>C++</code> could do something like this: <code>RootClass::call()</code>, <code>call</code> method is not static.</p>
  
  <p>I know there's <code>super</code> to access base class's property&amp;methods, is there anyway to access the <code>root</code> class method directly?</p>
  
  <p>thanks!</p>
