Functional Reactive Programming is an approach to writing programs. FRP uses signals, which represent a mutable value time-line of a value, and signal transformations as its basic blocks. 'fs2' is a functional streaming library for Scala.
This talk explores the key concepts of both FRP and 'fs2', how they relate to each other, whether we can write an FRP system on top of 'fs2', and what ideas from FRP can be used to guide future development of 'fs2'.
