I fully agree and would add: Component-oriented frameworks like React/Angular/Vue/… give you the ability to easily test your components individually (in the sense of unit tests or integration tests or manual tests / storybooks). Most classic templating languages for the backend don't offer anything similar and doing that would also be quite challenging: Most of the time the backend controller rendering/populating a given template is deeply entwined with business logic and database calls – good luck separating those concerns after the fact.
