Building a Standalone Vue 3 Reactivity Library: CycleJS‑like Reactive View, Immer‑like State, RxJS‑like Operators, and React‑Hooks‑like Mechanisms

This article explores Vue 3's function‑based reactivity API, demonstrates how to implement a lightweight, framework‑agnostic reactivity library with watchable objects, functional combinators, and immutable updates, and shows practical examples such as a reactive counter, a todo list, immer‑style state handling, RxJS‑style pipelines, and React‑hooks‑style utilities, while discussing the underlying concepts and limitations.
