Shared Component Logic

A deep-dive tutorial on sharing component logic across React, Angular, and Vue without introducing new APIs. Using a window size tracker as the running example, it covers how each framework handles reusable logic: React custom hooks (useWindowSize with useState and useEffect), Angular signal functions, and Vue composables using ref and the Composition API. The guide walks through data storage, side effect handling with event listeners and cleanup, and the rules governing custom hooks in React.
