What problem does it solve?

This Skill provides a deep understanding of Functional Reactive Programming (FRP) as the foundational paradigm for building interactive systems, unifying concepts like event sourcing, CQRS, and reactive streams under a single mathematical framework.

Core Features & Use Cases

• FRP Semantics: Explains the core principles of FRP, including behaviors, events, and their duality.
• Categorical Foundations: Details the underlying category theory structures (coalgebras, algebras, comonads, arrows, presheaves) that mathematically define reactive systems.
• Pattern Unification: Demonstrates how various architectural patterns (Event Sourcing, CQRS, Decider) are natural consequences of FRP principles.
• Use Case: Understand why reactive frameworks behave the way they do, enabling more robust and predictable system design for complex, time-varying applications.

Quick Start

Explain the core insight of Functional Reactive Programming, which is privileging change over state.
