title: Having a static variable in Backbone js views
body: <p>I am new to Backbone.js. I have this project where there is a hierarchy of multiple views and sometimes the views need to communicate with each other.
  After a little research on the Internet, I came across <a href="https://lostechies.com/derickbailey/2011/07/19/references-routing-and-the-event-aggregator-coordinating-views-in-backbone-js/" rel="nofollow">https://lostechies.com/derickbailey/2011/07/19/references-routing-and-the-event-aggregator-coordinating-views-in-backbone-js/</a> and tried to use the event aggregator. </p>
  
  <p>However, it didn't work. My guess is that the 'vent' is not the same instance across all the views. So, if there is any way to definine it as a static variable, I can probably make it work. So, is there a way to define static variables in Backbone.js?</p>
