Advanced Asynchronous Events

Before starting this, let’s see some questions:

• Why do I want to read this?

  This is the first real test for Observables. Typeaheads are an area full of bugs and complexity - can we solve that?

• What will I learn?

  How to apply the techniques from the last three chapters to solve a full, real-world problem.

• What will I be able to do that I couldn’t do before?

  Deal with state in an asynchronous world

• Where are we going next, and how does this fit in?

  Next, you’ll build an entire application - best get started!

Advanced asynchronous events

BANG! The starting gun goes off as two functions shoot down the track. Firing off AJAX requests, the competing functions zip around corner after corner until finally one reaches the finish line inches before the other.
