The Observable type and the operators that come with the libraries that implement them are extremely powerful and expressive tools to manage events in programs. Whether your application has lots of AJAX calls, socket events, worker threads, video and audio streams or just your standard mouse and keyboard events, using Observables can vastly reduce the number of bugs and lines of code you might have. You may even discover new features you didn’t think were possible!
To demonstrate the power and expressiveness of Observables to better manage asynchronous programming.
Possible choice 1) Any developer who has been to callback hell and back.
Possible choice 2) All developers who are interested in writing more fluent event based code
