Did I say that Ruby on Rails was the only option?

On the other hand, if a developer cannot figure out Ruby on Rails (or Sinatra, or Django, or Flask, or any of the PHP frameworks), and does not even know SQL, do they really have any business doing server-side web development?

Knowing JavaScript and one server-side web app framework/language is a pretty minimal requirement for a full-stack web developer. It boggles my mind to think that there are people working as professional developers that literally only know JavaScript. Those people should not be doing server-side development.
