Translating React
summary
Walks through React source and shows actual code paths: JSX transpiles via Babel into calls to React.createElement, createElement returns an object with type key ref props; react-dom.render delegates into the reconciler, Fiber is the reconciler that diffs and schedules updates; setState queues partial state updates and may be asynchronous; many protected attribute mappings live in a ~500-line table; secretInternals warns “do not use”; an anecdote notes a 250-line app ballooning to ~7,500 lines after a React rewrite.
