title: Get module.exports from within the same file
body: <p>In a file I have this code:</p>
  
  <pre><code>module.exports.greet = function() {...}
  </code></pre>
  
  <p>I want to use that function from within the same file.</p>
  
  <p>I thought this would work:</p>
  
  <pre><code>this.greet()
  </code></pre>
  
  <p>But it didn't.</p>
  
  <p>What is the reference I have to use?</p>
