It was a rhetorical question. I understand why we need to use a special version of setTimeout or a special HTTP module, but the fundamental problem is that Angular's "reactive javascript" abstraction leaks in a way that you're forced to do it the Angular way.
React's abstraction also leaks, which is evident when it doesn't automatically know to update itself so you have to call `setState`. But I'd choose this set of leaky abstractions over Angular's. Plus it makes it easy to spot all the places where the UI can change which is a huge plus for debugging. The beauty of React's set of abstractions is that it doesn't force you to do things a certain way (use $http, use $timeout) or use observables which embraces mutability.
Also to further my point that Angular (and any other framework that provides templating) doesn't embrace javascript, every time you use `ng-repeat` you're not doing javascript. You can't put a debugger in the middle of the loop to check the scope. You can't use Immutable-js because `ng-repeat` loves arrays. (Ok you can convert the immutable to an array before hand, but then when it changes you'd have to incur an expensive rerender of the list) You can't use static analysis tools.
