Arrow

Push-pull Signal Function FRP.

Goals

• Learn about Signal Functions, Signal Vectors, Arrows, and Profunctors
• See if Signal-Function / Arrowized FRP is a viable approach to interactive apps in JavaScript

Design goals

• Implement sound FRP semantics with a pure foundation (as far as possible in JS)
  • Avoid bugs, race conditions, and glitches
  • Push impurity and IO to the edges
• Balance JavaScript's event-driven nature with the simplicity and predictability of programming with continuous values and total functions
  • Use a push-pull approach instead of either pull-only, or push-only
• Favor composition as a base programming API
  • Provide a core set of operators with rigorous semantics as building blocks
  • Assemble higher level operations by composing existing ones
