Functional Reactive Programming Basics

This lecture introduces the basics of functional reactive programming (FRP) through the development of a simple implementation of Signals and Vars, which are fundamental to FRP. The lecture covers the APIs for Signals and Vars, implementation details, dependency maintenance, creating signals, signal variables, and evaluating signals. It also discusses how to find out on whose behalf a signal expression is evaluated, implicit function types, and provides a summary of FRP with examples and implementation details.
