Error Handling with Observables

When we issue an http request to get or update data, there is always the chance that something will go wrong! The item the user requested isn't found, the updated data doesn't pass the server-side validation, our boss hasn't paid the electric bill and our server is down ...

We look at several scenarios: Catch and Rethrow, Catch and Continue, Retry on Error, and Action Streams
