I agree. He does not say. That it&#x27;s an old pattern is probably a testament to its strength.<p>I am using React&#x2F;Flux (Redux) as well. I generally love it and find it easy to write dynamic UIs and without making very many mistakes. Each React and Flux  component is small, focused,  testable, and easy to reason about.<p>The only gripes I have are the small amounts of boilerplate I end up with. Redux cuts this down a lot over a homebrewed Flux implementation I wrote. Also, testing complex trees of components can be a bit of a drag.
