一句话：为 React Hooks 核心机制提出操作语义，并实现解释器与可视化工具以澄清其行为。
React Hooks 负责函数组件中的副作用管理，但其语义对开发者常不透明，易导致 UI 缺陷。本文提出 React-tRace，对 React Hooks 的核心机制进行形式化，给出操作语义以阐明其行为。作者从理论上证明该模型体现 Hooks 的关键性质，并通过定义式解释器与测试套件进行实证比较，说明其能捕捉 React 的实际行为。最后，基于该形式化实现可视化工具，展示开发者如何更直观地理解 Hooks 的语义。
React has become the most widely used web front-end framework, enabling the creation of user interfaces in a declarative and compositional manner. Hooks are a set of APIs that manage side effects in function components in React. However, their semantics are often seen as opaque to developers, leading to UI bugs. We introduce React-tRace , a formalization of the semantics of the essence of React Hooks, providing a semantics that clarifies their behavior. We demonstrate that our model captures the behavior of React, by theoretically showing that it embodies essential properties of Hooks and empirically comparing our React-tRace -definitional interpreter against a test suite. Furthermore, we showcase a practical visualization tool based on the formalization to demonstrate how developers can better understand the semantics of Hooks.
