Functional Programming in JS w focus on Reactive Programming (Rx in JS)

What's 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 talk 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

In this talk we'll be exploring the Reactive Extensions (Rx) library (https://rx.codeplex.com/) which allows us to treat events as collections. You'll learn patterns you can use on both the client and the server, allowing you to build end-to-end reactive systems.
