In the previous chapter, you learned the very basics of functional reactive programming, using the bacon.js library. We discussed what is an observable and saw two different flavors of it in the bacon.js library (EventStream and Property). We also looked at how to create observables from common event sources (interval, array, or user input) and even from any other possible source ( using the fromBinder() method).
After an introduction to observables, we looked at how to subscribe to it. You can react to events, errors, or even detect the end of an observable when you subscribe to it. So, you learned how to create an observer for your observables.
One of the really important lessons ...
