This summary provides a concise overview of the article, which discusses the concept of closures in JavaScript and how they relate to React Hooks. The author creates a tiny clone of React Hooks using closures, demonstrating their effective use and how Custom Hooks naturally arise. The article explains how closures are used in the implementation, including the Module pattern and the usage of arrays to generalize state and effects. It also touches on deriving the rules of hooks based on the implementation and concludes that understanding closures can help demystify how React Hooks work.
