 **Using Iris MVC for code reuse** 
 
 By creating components that are independent of one another, developers are able to reuse components quickly and easily in other applications. The same (or similar) view for one application can be refactored for another application with different data because the view is simply handling how the data is being displayed to the user.
 
 If you're new to back-end web development read about the MVC architectural pattern first, a good start is that [wikipedia article](https://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller).
