title: Node module.exports reference own function like this keyword?
body: <p>I have the following code:</p>
  
  <pre><code>module.exports.functionA = function(str) {
       console.log(str);
  }
  </code></pre>
  
  <p>In the same module, how do I call functionA? In other languages such as PHP, you can call another member of the same class using $this->functionA();</p>
  
  <p>This does not work:</p>
  
  <pre><code>module.exports.functionA('Hello world!');
  </code></pre>
