What It Defines

The living standard defining HTML: document structure, elements, form processing, browser APIs (history, navigation, storage), workers, cross-document communication, and parsing rules.

Canonical (Normative)

HTML LS §WorkersWHATWGShould Know

Web Workers

Any CPU-intensive work (parsing, compression, crypto, WASM) must run off the main thread to keep UI responsive. Workers are the browser's concurrency primitive — understand their message passing model and limitations (no DOM access).

HTML LS §HistoryWHATWGShould Know

History API

Every SPA router (React Router, Next.js, Vue Router) is built on pushState/popstate. The Navigation API is the modern replacement with better intercept semantics. Understanding the history stack prevents navigation bugs.
