`useMemo` and Stable Values

This technical article discusses a common pattern in custom React hooks: returning a tuple of [state, handlers]. It focuses on why the author uses `useMemo` to create a stable object of handler methods, arguing it provides a simpler and more performant API than defining individual functions with `useCallback`. The post includes code examples from a `useSwitch` hook and explains the benefits of stable reference values for preventing unnecessary re-renders.
