This is a very good question.<p>I can&#x27;t say for Angular but the thing about React is that it is the V in MVC. The fact that JSX apparently mixes JS (logic) and HTML&#x2F;CSS (presentation) is kind of a red herring. The JS logic in JSX is actually the view logic, not but domain logic!<p>Also, as an experiment you can prove to yourself that you can separate out all the actions, views, and states in React. Here states=model, views=view actions=controller -- but wait you say, this is MVC so React is in fact MVC and not V! No! The thing is MVC can be arranged hierarchically into levels, so you can have M(MVC)C... if you like :) Don&#x27;t believe me?
