What this episode covers

Sam and Ryan talk more about their recent experience working with React Hooks. They dive into useEffect, talk about how the hooks paradigm encourages UI developers to think about their application's side effects declaratively, discuss whether the paradigm is too much of a departure from real-world stateful UI development, and compare it to working with side effects in Ember applications.
