title: should I use the constructor or the instance when referencing an object's property from another constructor?
body: <p>While I am writing a constructors' methods like the "runGame" method of the "Game" constructor, if I need to reference a property of the "GameBoard" constructor should I use the name of the constructor, like this:</p>
  
  <pre><code>function Game(){
     this.runGame(){
       var someProp = GameBoard.otherProp;
     }
  }
  </code></pre>
  
  <p>or do I have to create an instance of the constructor object first and then refer to the instance like this.</p>
  
  <pre><code>var newGameBoard = new GameBoard();
  
  function Game(){
     this.runGame(){
       var someProp = newGameBoard.otherProp;
     }
  }
  </code></pre>
