    Introducing the Observable

    rxjsRxJS
    ^2.3

    In this lesson we will get introduced to the Observable type. An Observable is a 'collection that arrives over time'. Observables can be used to model events, asynchronous requests, and animations. Observables can also be transformed, combined, and consumed using the Array methods we learned in the previous lessons. We can write powerful and expressive asynchronous programs using the few simple methods we've learned so far.
