title: How can I implement a method from a class I extend from in Typescript?
body: <pre><code>class Abc {
      doTask() {
          return 1;
      }
  }
  
  class Def extends Abc {   
      // How can I access doTask() here?
  }
  </code></pre>
  
  <p>I would like to implement that method doTask() inside of the class Def.  Can someone give me advice on how I can do this.</p>
