title: How to create a constructor function in javascript so that if two instance created with 'new' keyword the value of instance1 === instance2 return true
body: <p>I was finding a way, if I can make this code work. I cannot use prototype and I want to create the instance using "new" keyword only.</p>
  
  <pre><code>function Employee(name) {
      this.name = name;
  }
  var e1 = new Employee();
  var e2 = new Employee();
  e1 === e2; // Expected result should be true.
  </code></pre>
