Formerly called "functional reactive programming" (FRP).
But the meaning associated with the term drifted so far away from the original idea that
it was renamed to "denotative continuous-time programming" (DCTP).
Definition
(Taken from Conal Elliotts' slides)
Two fundamental properties of DCTP:
- Precise, simple denotation. (Elegant & rigorous.)
- Continuous time. (Natural & composable.)
Not DCTP:
- graphs
- updates and propagation
- streams (since they are a discrete model, despite the name)
- doing
