I feel worried reading this post, because it doesn't seem like you have separated impulsive emotional responses from objectivity, and when I see engineers have this behavior, I believe it masks our ability to asses technology well. For example mixing view logic with view templates, both in the view concern, (and the concept of a DSL), follow computer science principles of domain/concern separation, vs separation of technologies like ("html" and "js", which isn't even fully accurate for JSX), is not a computer science principle, and has no benefit when separated.
