title: How create static functions/objects in javascript/nodejs (ES6)
body: <p>I want to create a static class using Javascript/Node JS. I used google but i can't find any usefull example.</p>
  
  <p>I want to create in Javascript ES6 something like this (C#):</p>
  
  <pre><code>public static MyStaticClass {
     public static void someMethod() {
        //do stuff here
     }
  }
  </code></pre>
  
  <p>For now, I have this class, but I think that this code will creates a new instance every time that it be called from "require".</p>
  
  <pre><code>function MyStaticClass() {
     let someMethod = () =&gt; {
        //do some stuff
     }
  }
  var myInstance = new MyStaticClass();
  module.exports = factory;
  </code></pre>
