4. Reactive Framework “Rx is a library for composingasynchronousand event-based programs using observable collections.”

5. Observable Collection - Common Uses

6. Flavors of Rx JavaScript

7. Pulling with Enumerables False var query = from candy in bagOfCandies where candy.HasNuts group candy by candy.Name into GroupedCandies select new {Name = GroupedCandies.Key, CandyCount = GroupedCandies.Count()}; foreach (var aggregate in query) Move Next Move Next Move Next Move Next

8. IEnumerator vs. IObserver public interface IEnumerator { object Current { get; } bool MoveNext(); void Reset(); } Blocking public interface IObserver<T> { void OnCompleted(); void OnError(Exception exception); void OnNext(T value); }

9. Pushing with Observables var query = from candy in bagOfCandies where candy.HasNuts group candy by candy.Name into GroupedCandies select new {Name = GroupedCandies.Key, CandyCount = GroupedCandies.Count()}; query.Subscribe(group => DoSomething(group)); OnCompleted OnNext OnNext OnNext OnNext Subscribe OnNext
