He debunks five common myths: that signals require compilation magic, that they don't scale, that adding signals makes frameworks faster, that the React compiler is equivalent to signals, and that virtual DOM can do things signals cannot. Key insight: signals enable fine-grained rendering where only specific DOM nodes update on state change, unlike React where state ownership causes component subtrees to re-execute. The React compiler improves memoization but doesn't change React's performance ceiling, while signals are intrinsically faster by doing less work. ## Full article daily.dev links to this article rather than hosting it.
