In this chapter, we simulated a real-world application with our stock market program. We've written it in a somewhat traditional way using thread pools and a custom queue implementation. We then refactored it to a CES style using RxClojure's observable sequences.

The resulting program is shorter, simpler, and easier to read once you get familiar with the core concepts of RxClojure and RxJava.

In the next Chapter we will be introduced to core.async in preparation for implementing our own basic CES framework.
