Staying Current: Reading Specs and Proposals
Follow TC39 proposals, read W3C drafts and browser compatibility tables, subscribe to newsletters like CSS-Tricks and web.dev, and evaluate new tools critically.
Why Frontend Devs Need to Read Specs
Frontend changes fast. New CSS, JS, and browser APIs ship every quarter. Senior engineers don't wait for blog posts — they read the source: W3C drafts, TC39 proposals, CSS WG specs, browser implementation status pages.
TC39 — JavaScript's Process
TC39 is the committee that evolves JavaScript. Proposals go through 5 stages: 0 (strawperson), 1 (proposal), 2 (draft), 3 (candidate), 4 (finished, shipped in ECMAScript). Stage 3 is when it's safe to bet on (browsers implement, syntax frozen).
