React compares virtual DOM trees using an O(n) heuristic algorithm based on element types and keys, calculating minimum real DOM mutations needed.
Middleware functions have access to the request object, response object, and next middleware function, used for logging, authentication, request validation, and CORS handling.
useEffect runs asynchronously after the render has been committed and painted to the screen. useLayoutEffect runs synchronously immediately after DOM mutations, before browser paint, preventing visual flicker.
