Getting Closure on Hooks
summary
Builds a working React Hooks clone in 29 lines of readable JavaScript, using plain closures, a module-wrapped hook store, and an index-based hook array to support multiple hooks and useState and useEffect semantics. Implements a tiny JSX createElement, a simple work loop to re-render to the DOM, and a custom data-fetching hook for images, all running in CodeSandbox. The claim is practical and demonstrated: it actually works end-to-end.
