It depends on your perspective. If you&#x27;re building an application that passes disjointed components around, then yes, you can combine the three (js,html,css) into a self reliant container. If you&#x27;re building a website that is basically a series of pages, that is part of a book per say, then it doesn&#x27;t quite make sense. I would say 10 years ago it was not common to think of the web as a platform. Over the last 5 years using the dom as platform and js as the source code has become much more predominant.<p>Whether the scope of your business can be used by this architecture would determine whether it would come up in your day to day.
