title: Use of this.function inside module.export
body: <p>How can I use functions and target them inside module.exports in Node.JS ? Says the function is not defined.</p>
  <pre><code>module.exports = (args) =&gt; {    
  
       this.myFunction = function(int){
            return int++;
       };
  
       let test = this.myFunction(5);
  };
  
  // this.myFunction is not a function
  </code></pre>
