This doesn't mean Node.js is the right solution for all websites. Small business or local organization websites that have low volume should use none of those web stacks, but rather a content management system like Wordpress which requires no programming at all. And someone who is already a Python expert may be most at home with a Python based framework like Django or Flask. A Ruby on Rails expert may be best served continuing to use Ruby on Rails. But if there was one language and framework stack that all web devs should know in addition to any others they may know or like, we believe this is it.
