reactjs/react-basic: A description of the conceptual model of React without implementation burden.

A theoretical exploration of React's conceptual model that breaks down UI development into fundamental concepts like transformation, abstraction, composition, state management, memoization, and algebraic effects. The document presents React as a system for transforming data into UI representations through pure functions, emphasizing how complex interfaces can be built through composition of simpler abstractions. It covers advanced concepts like memoization for performance optimization, state management patterns, and introduces algebraic effects as a way to handle cross-cutting concerns like theming without prop drilling.
