Answer 1

render method inherits from extends Component??

No, you must define this method yourself.
Because it's a lifecycle method, and like all lifecycle methods, it's called by the library's internal implementation. You can read more about the React.Component lifecycle here .

Answer 2

There is a creation (and not a call) of the render method that returns JSX, and JSX is processed somewhere and somehow.
