Controlling Time and Space: understanding the many formulations of FRP

Functional Reactive Programming (FRP) is becoming an increasingly common way to structure event-driven code, but the term "FRP" actually refers to a large body of increasingly diverse work. This talk will quickly cover the basics of FRP, and then go into a couple different formulations of FRP that people are beginning to use. We will explore how these formulations fit together historically and theoretically.

Finally, we will see how the particular variation of FRP used in Elm makes it easy to implement hot-swapping and Elm's Time Traveling Debugger.
