Hydration, Islands, Streaming, Resumability… Oh My!
summary
Islands limit client JavaScript and often cut time‑to‑interactive by shipping mostly SSR HTML and hydrating only widgets like comments or share buttons; Astro defaults to zero JS and parallel island loading. Streaming SSR lets fast parts render before slow ones, and Marko pioneered streaming plus automatic partial hydration. Resumability (best known from Qwik) serializes server state, attaches minimal lazy event handlers, and avoids replaying application logic so the client downloads far less code.
