Lightning talk version of FRP in JS - skips behaviors and focuses on Events

1. LIGHTNING TALK
SFJS 2012

2. Lightning is a giant discharge of electricity
The spark can reach over five miles in length, raise the
temperature of the air by as much as 50,000 degrees
Fahrenheit and contain a hundred million electrical volts
It is estimated that Earth as a whole is struck by an average of
more than a hundred lightning bolts every second
Lightning is not confined to thunderstorms. It's been seen in
volcanic eruptions, extremely intense forest fires, surface
nuclear detonations, heavy snowstorms

3. BETRAY HUMANITY WITH
FUNCTIONAL REACTIVE
PROGRAMMING

4. RIDICULOUSLY BRIEF HISTORY
Conal Elliott & Paul Hudak write Fran
A bunch of libraries are made (Reactive Banana, Yampa, etc)
Conal writes Push/Pull paper to address issues.
Eric Meijer & Friends make it more accessible starting with C#,
then js
Lots of other frameworks made (Knockout, RxJs, Bacon, Flapjax)
I’m talking to you now

5. SO... WHAT IS IT?

Stateless
Asynchronous
Explicit event streams
Compositional
Explicit time
Identity over time
Data flow modeling
