Like an Event, an Observable is a sequence of values that a data producer pushes to the consumer. However unlike an Event, an Observable can signal to a listener that it has completed, and will send no more data.
Querying Arrays only gives us a snapshot. By contrast, querying Observables allows us to create data sets that react and update as the system changes over time. This enables a very powerful type of programming known as reactive programming.
Disposing of a Subscription object unsubscribes from the event and prevents memory leaks. Disposing of a subscription is the asynchronous equivalent of stopping half-way through a counting for loop.
If we convert Events to Observable Objects, we can use powerful functions to transform them.
