I just don&#x27;t understand how anyone can make a &quot;best&quot; decision these days.<p>I&#x27;m not a frontend person. I&#x27;m backend and middleware and infrastructure, although I&#x27;m trying to figure out the front end stuff.<p>Maybe I just don&#x27;t understand what people are trying to accomplish. In fact, I&#x27;m sure of that. I can&#x27;t for the life of me figure out why you would want to have your front end so tightly coupled to you database.<p>Can someone explain to me in simple terms how and where I would use one of these JS frameworks in the context of a Python or Golang or Ruby&#x2F;Rails app?
