React is leveraging Functional Reactive Programming concepts, with the use of lifecycle and other conventions that basically make it easy to reason about events and their effects. Every click/scroll will have an effect on the app state and/or network call, and I actually think a sufficiently complex enough app would end up with React-like patterns or the alternative which is much worse, a ton of repeated code and logic.
