In this chapter, we looked at a real use case for Reactive applications: building a dashboard for AWS CloudFormation stacks.

We have seen how thinking of all the information needed as resources/items flowing through a graph fits nicely with how one creates Observables.

In addition, by creating primitive Observables that do one thing only gives us a nice declarative way to combine them into more complex Observables, giving us a degree of reuse not usually found with common techniques.

Finally, we packaged it together with a simple Om-based interface to demonstrate how using different abstractions in the same application does not add to complexity as long as the abstractions are chosen carefully for the problem at hand.

This brings us to the end of what hopefully was an enjoyable and informative journey through the different ways of Reactive Programming.
