React The Good Parts
summary
Starts with a hand‑built counter then shows a 10,000‑item list demo comparing React to Solid and claims React’s slowness is the virtual DOM plus whole‑tree rerenders unless memo or similar are applied. Shows that using useState naively reruns parents, while createSignal gives fine‑grain updates. Implements a tiny server that uses renderToString, explains awaiting async components to realize server components, and demonstrates server rendering plus client hydration to deliver SEOable markup and soft navigation.
