Tutorial: [SOLD OUT] Reactive programming in JavaScript

This tutorial is sold out.

What does a mouse drag event have in common with an Array of numbers? The answer to this question may surprise you: they are both collections. This key insight holds the key to dramatically simplifying asynchronous programming in Javascript. In this tutorial you will learn how you can use the familiar Javascript Array methods to create surprisingly expressive asynchronous programs. Using just a few functions, you will learn how to do the following: Declaratively build complex events out of simple events (ex. drag n' drop), Coordinate and sequence multiple Ajax requests, Reactively update UI's in response to data changes, Eliminate memory leaks caused by neglecting to unsubscribe from events, Gracefully propagate and handle asynchronous exceptions.
