-The main takeaway is that `ASQ.react(..)` is a lightweight adaptation of F/RP concepts, enabling the wiring of an event stream to a sequence, hence the term "reactive sequence". Reactive sequences are generally capable enough for a lot of basic use-cases. If you're looking for more advanced reactive programming, check out RxJS and other similar libraries.
