Seperations of concerns can be interpreted in multiple ways. You could say that the concern of one React component is to render one particular part of a view based on data. Or: "convert data to a view".

In for instance Angular you have the template seperated from the controller or directive. But in what way does that really help you? The controller and the template are inseperable. The variables inside of the template corrospond directly to the variables in the scope of the controller. You cannot see what the template is doing without having the controller next to it. In React you really see how the view is built up, without any magic.

The points you make on React make me really wonder if you did your research.
